Sophisticated radiology in otolaryngology. II. Diagnostic imaging: non-roentgenographic (non x-ray) modalities (ultrasound, nuclear medicine, thermography).

Newer forms of radiologic diagnostic imaging now include non-roentgenographic modalities such as ultrasound, nuclear medicin, and thermography, all of which can be applied to otolaryngology. It is the purpose of this presentation to demonstrate these modalities, and indicate their clinical application, yet in its earliest stages, to otolaryngology.

[Value of rheovasography and thermography in the diagnosis of varicose veins of the legs in the practice of expert evaluation of work capacity].

The article deals with the problems of using such new modern diagnostic methods as rheography and thermography in objective assessment of the degree of functional disorders in patients with lower limb varicosis. The authors describe the examination method, the necessary apparatus, and the evaluation of the qualitative and quantitative parameters on the basis of the information obtain. The results of the examination provide the possibility to determine exactly the degree of chronic venous insufficiency, judge the condition of the valvar apparatus of the veins, appraise the compensatory possibilities of the vascular wall and the clinical prognosis, and consequently, to solve more objectively the questions of expert medical assessment of the working capacity.

Liquid crystal thermography in the localization of undescended testicles.

Liquid crystal thermography (LCT) for the localization of undescended testicles was performed in 28 patients, in 21 of whom ultrasonography (US) was also performed: Among the 21 operated cases, LCT correctly localized the testicles in 19, and US in 18 cases. LCT may be used in screening for undescended testicles.

"Bony sciatica"--the value of thermography, electromyography, and water-soluble myelography.

With an increased interest in sporting activity, particularly among the older population, together with the appreciation of the importance of "bony entrapment" as a cause of sciatica, so the need has arisen to develop a simple, noninvasive, reliable, and reproducible method of determining whether leg pain is of radicular or referred origin. In our experience, liquid crystal thermography has proved unsatisfactory but electromyography appears to be of value in distinguishing root from referred pain in approximately 70 per cent of patients within this group. Our experience with radiculography within this context is also presented and is shown to be currently unsatisfactory.

Liquid crystal thermography of the breast.

In a retrospective study 19461 patients were examined. 2002 patients were clarified by biopsy and histological examination; 500 patients underwent aspiration cytology. The accuracy rate of thermography is 67.8% for malignant and 70.6% for benign lesions. False negative findings were given in 13.9% and false suspicious in 6.8%. False suspicious findings were mostly seen in inflammation, cysts and/or proliferation. The criteria of malignancy by "Tricoire" were examined. It can be shown, that their predictive value is very good. This especially if the "disturbance of thermoregulation" is examined carefully.

[Thermography and radionuclide scintigraphy in reconstructive plastic operations following radical mastectomy].

Thermography is quite an informative and reliable method of examination of patients after reconstructive-plastic breast operations. It makes it possible to assess, with a sufficient degree of assurance, the blood circulation in a skin-muscular graft of the broadest muscle of the back, to diagnose capsule constrictive fibrosis, to detect foci of hyperthermia at the edge of endoprosthesis in the presence of bulky formations hidden by an implant, and can be recommended for the screening of such patients. In some cases scintigraphy makes it possible to differentiate between tumor and non-tumor origin of foci of lesions detected in endoprosthesis.

[Terminology problems in medical thermography].

The paper is devoted to some problems of medico-technical terminology of clinical thermography. A short historical review of stages of the discovery of infrared rays and their medical application was given. An analysis of a number of terms is based on the rules of medical terminology and state standards. An obligatory use in literature of correct terms, mainly of the Greek and Latin origin, is proposed. Commonly used terms on the basis of modern anatomical terminology are recommended for thermogram description.

Thermography of gluteal regions after hypogastric artery ligation.

Thermographic examination of buttocks of 7 patients after hypogastric artery ligation using non-absorbable suture has been performed. In 6 patients the possibility of eventual recanalization has been eliminated by aortography, in 1 patient by pelvic angioscintigraphy. Repeated thermographic examination of 3 patients after bilateral ligation has shown no anomalous results. In 1 among 4 patients after unilateral ligation a cooler area could be repeatedly observed on the ipsilateral side. Thermography, in combination with other methods of examination, seems to be suitable for complex study of the state of circulation after hypograstric artery ligation, performed to stop a life-threatening hemorrhage.

Diagnostic value of infrared thermography in breast cancer, and in proliferative and non proliferative mastopathies.

The authors present the results of breast examinations in 201 female patients controlled by cytology and histology. Based on their results obtained by an AGA 680 type infrared thermography, their conclusion was that the method is primarily suitable for the examination of biological thermogenesis, one of the functional characteristics of tumours. Some T1 breast cancer of the same histological type are thermographically "silent", i.e. display no pathological alterations. Thermographical signs characteristic of carcinomas are to be found only in 60-70% of the cases. It is explained by the biological heterogeneity of tumours, i.e. the amount of heat generated by the metabolic processes of the different carcinomas is not equal, as well as they are different in vascularization and as a consequence of it in their heat conduction parameters. Similar reasons explain the appearance of different thermographic patterns--negative or characteristic of cancerous alterations--in proliferative mastopathies.

Reflex sympathetic dystrophy: electronic thermography as an aid in diagnosis.

Reflex sympathetic dystrophies can be distressing conditions for patients as well as physicians. In the full-blown case, the diagnosis is easy to make; however, many more subtle forms of reflex sympathetic dystrophy exist. In the full-blown case, diagnosis may be quite simple when the physical findings are present. In the more subtle forms, however, one must have a high index of suspicion in order to make the diagnosis. Clinical testing, such as stellate ganglion blocks, may or may not be helpful. Electronic infrared thermography emerges as a helpful tool in the aid to diagnosis. We have presented several cases in order to illustrate this.

[Computer tomography, echography and thermography in the diagnosis of extrarenal complications in a transplant].

Computed tomography, echography and thermography were used for detection of extrarenal complications in 22 patients at different time after kidney transplantation. Morbid perirenal formations were found in 12 patients (hematoma in 4 patients, abscess--in 2, lymphocele--in 5, urinoma in 1). The complex of these methods allows to detect and establish the character of the peritransplant fluid collections.

Diagnostic and prognostic role of infrared thermography.

A series of 469 breast cancer studied by physical examination (PE), mammography (M) and infrared thermography (TH) is discussed. Follow-up was performed up to 5 years later. The poor diagnostic role of TH is proven for the low sensitivity in the total series (0.47) and, particularly, in T1 cancers (0.26). TH does not increase significantly the cumulative sensitivity (0.98 vs. 0.97 in the total series). Its limited advantage is offset by the great number of useless biopsies due to TH false positive. A correlation between TH pattern and prognosis is evident only when TH is considered independently from other reliable prognostic indicators such as the T or N categories. If survival curves are stratified by T or N or if a multivariate analysis based on TH, T and N variables is performed, all correlations between TH pattern and prognosis disappear; for this reason the use of TH as a prognostic indicator in the clinical practice is disregarded.

[Diagnostic value of thermography in diseases of the vessels of the lower extremities].

The thermographic examinations of 430 patients with different diseases of the lower extremity vessels have confirmed the diagnostic value of thermography. The method was shown to give the objective assessment of alterations in blood circulation of the lower extremity resulting from a pathological process. It may be widely used for diagnosis and control of treatment of vascular diseases.

[Use of color contact thermography for diagnosing aortic and iliac artery diseases].

The coloured contact thermography may be used as an additional method for diagnosis of diseases of the abdominal aorta and its major branches. In cases with aneurysms of the abdominal aorta the coloured thermograms showed the increased skin temperature of the frontal abdominal wall over its projection. The method may be used for differential diagnosis of the aneurysm and occlusion of the abdominal aorta.

Tamoxifen responders selection by computerized contact thermography in benign breast disease.

Initial thermic breast values recorded by contact thermography in 29 premenopausal patients with benign breast disease were compared to those recorded 4 and 24 hours after a single 20 mg tamoxifen oral administration. Programmes worked out by the thermographic Prometheus computerized system processed the thermic values. The data obtained were analyzed and compared to the clinical effects resulting from 2 or 3 tamoxifen therapeutic cycles subsequently administered to these patients. The results obtained so far are indicative of the possibility to differentiate by thermographic means the responders from non-responders to subsequent tamoxifen-therapy for breast benign disease.

[Role of thermography in the evaluation of the results of the surgical treatment of patients with arteriosclerosis obliterans].

The Soviet thermovision device "Rubin-2" supplied with a special set for quantum processing of the thermovision picture was used for examination of 60 patients with obliterating atherosclerosis, 30 of them were subjected to restorative operations on the lower extremity vessels, 30--to uni- or bilateral lumbar sympathectomy. Results of thermovision examinations were compared with findings of the clinical examination, angiography, length-wise rheography. High degree correlation between normalized peripheral blood circulation and data of thermography is noted. The method of thermovision allows to objectively estimate results of the surgical treatment of obliterating atherosclerosis of the lower extremity vessels and may be successfully used in practical medico-occupational examinations.

[Infrared thermography in malignant melanoma. Diagnostic potential and limits].

Using infrared thermography, 264 in patients who were clinically suspected of having primary malignant melanoma (mM) of the skin were examined with regard to the thermographic pattern of both tumor and peritumoral skin area. In 84% of the patients with histologically confirmed mM deviations from normothermic pattern (mainly hyperthermic) were found of the tumor itself and/or the peritumoral area. All nodular mM proved to be hyperthermic. Pigmented skin tumors other than mM (e.g., angioma, basalioma, nevus cells, mole, histiocytoma) predominantly exhibited local isothermia or only minor thermographic changes. The infrared radiation intensity of the mM depended on the individual surface attributes of the tumors. As a rule, the larger mM are warmer than small mM. When comparing histological staging of a mM with thermographic classification, the pT values were strongly correlated with the thermographic values, ranging from Q1 to Q4. The highest measurements of infrared radiation were obtained in the nodular and acrolentiginous mM, as compared to the other melanoma types. There is evidence that mM exhibiting marked local hyperthermia have a particularly to poor prognosis.
