Multiphase skeletal scintigraphy in primary fibromyalgia syndrome: a blinded study.

Sixteen patients with primary fibromyalgia syndrome were assessed blindly by multiphase skeletal scintigraphy to detect possible subclinical synovitis and uptake abnormalities at tender point sites. Results were normal in 14 of the 16 patients. Mild and localized abnormalities were found in 2 patients and were possibly due to the trauma of overuse. Our multiphase skeletal scintigraphy study showed that synovitis, other evidence of arthritis, or abnormalities at tender point sites were not increased above normal expectation among our sample of patients studied with fibromyalgia.

Complementary roles of radionuclide and computed tomographic imaging in evaluating trauma.

For 6 consecutive months all triage acceptable emergency room patients at the St. Francis Medical Center with blunt or penetrating trauma involving the abdomen were included in this review. Computed tomography and radionuclide imaging of the abdomen and urinary tract was performed in addition to the usually indicated diagnostic procedures. In our hospital the Radiology Department is adjacent to the Emergency Department. Close cooperation of the trauma team, the imaging physician and the technologists, has provided a stable, reproducible pattern in the performance and evaluation of nuclear medicine and radiographic techniques. Teleradiologic techniques of image transmission over the telephone lines permits immediate availability of the expertise of the radiologist. This correlation has provided an opportunity for improving patient care and refining our protocol in the care and management of the acutely traumatized patient. One-hundred-twenty-seven patients classed as acute trauma cases were processed during those 6 mo. Forty-two of these patients were not included in this study. They were triaged as immediate surgical emergencies, had incurred injury limited to the head, extremities or thorax, or were not injured sufficiently to require the special care of the designated trauma team. The 85 patients in this study included 56 males and 29 females. The patient age ranged from 3- to 71-yr-of-age. The median age was 29.3 yr. The author feels the findings in this evaluation of the complementary roles of radionuclide imaging and computed tomography should be of value to others in the formulation of their acute trauma care protocol. Nuclear medicine techniques retain an important role in the diagnosis of several sequelae of head trauma. Sensitivity and accuracy for detection of subdural hematoma are not as high as those of transmission computed tomography even if proper techniques are employed. Other important applications, however, include the diagnosis of normal pressure hydrocephalus, location of cerebrospinal fluid leakage, and confirmation of brain death.

A prospective study comparing nuclear scintigraphy and computerized axial tomography in the initial evaluation of the trauma patient.

Eighty-five consecutive patients admitted for trauma evaluation and fulfilling criteria suggesting the possibility of intra-abdominal injury underwent both immediate computerized axial tomography of the abdomen and a nuclear medicine evaluation, including a liver-spleen scan with or without a renal scan, in order to delineate their injuries and direct management. The limitations, advantages, and complementary use of each modality in the initial evaluation of the trauma patient is described. Overall, nuclear scintigraphy excelled in instances of contusion, in the evaluation of the restless or uncooperative patient, and in children. With computerized tomography, the retroperitoneal structures were well defined and multiple abdominal injuries could be seen. Neither modality demonstrated the presence of intra-abdominal fluid consistently. No patient with assumed isolated liver, spleen, or renal injury on the basis of the above studies, who was managed nonoperatively, required subsequent laparotomy.

Nuclear medicine and complementary modalities in renal trauma.

The diagnosis of renal trauma for many years was achieved through history, clinical findings, the performance of a survey film of the abdomen, urinalysis, excretory urography, aortography, and selective renal artery arteriography. The development of the scintillation camera and the availability of 99mTc, as well as 99mTc labeled pharmaceuticals, approximately fifteen years ago has widened this diagnostic horizon. Exquisite new imaging modalities have become available recently. As a result of constantly improving technology, these techniques--including computed tomography, sonography, with real time enhancement, and digital video subtraction angiography--are utilized more and more frequently. The full impact of these newest wonders is not yet realized. Cost-effectiveness, radiation exposure, accumulative drug side-effects, availability of facilities and personnel and professional and technical training have become major considerations.

Peritoneal lavage and scintigraphic evaluation of blunt abdominal trauma.

The emergency management of blunt abdominal trauma requires rapid assembly of accurate information. But history, physical findings and conventional tests may be unreliable. As a result, peritoneal lavage is an integral part of the initial diagnostic protocol in many centers. However, confusion in interpretation, especially of "weak positives," can result in delayed or unnecessary celiotomy. In our regional trauma center, lavage is now reserved for selected cases based on experience with 1,833 cases "scanned" during a five-year period. The indications, contraindications, techniques, interpretation, advantages, disadvantages, and complications of lavage and scanning are presented. A protocol using radionuclide imaging for initial evaluation of blunt abdominal trauma is proposed and representative case studies are included to support this approach.

99m-Technetium phosphate compound joint scintigraphy in the management of juvenile osteochondritis dissecans of the femoral condyles.

The known sensitivity of joint scintigraphy in following the course of fracture healing caused the authors to believe that this radiologic technique might be valuable in the management of osteochondritis dissecans (OCD). Accordingly, 99mTc-diphosphonate joint scintigraphy was used on 18 patients with OCD of the knee. The average age was 13 1/2 years. The scintigrams were repeated at 6-week intervals until healing had occurred. When the diagnosis of OCD was established by standard roentgenograms and joint scintigraphy, the patients were placed on an activity restriction program, attempting to reach a symptom-free level. The patients were followed for an average of 18 months. Ninety-five scans were categorized according to their level of scintigraphic activity. This led to a discrete four-part scintigraphic classification that is indicative of the extent of healing or progression of this condition, and precedes changes seen on standard x-rays by months. Joint scintigraphy also rules out anomalies of ossification in the diagnosis of OCD since an anomaly should have a normal scintigraphic appearance. We have concluded that joint scintigraphy is valuable in the management of OCD because of its superior sensitivity to changes in the activity of the lesion. As experience is gained with this technique, those cases that should be prophylactically surgically stabilized may be indicated.
