[Urethral echography: potential and limitations].

Since in the early years of 1980, the diagnostic for images about male's urethral injury was exclusively assigned to urethrocystography. Sially in repeated check the gonads too often are exposed to ionizing radiations. Our results show urethrocystography/ultrasonography good correlation (13/15) cases) with 86% sensibility. Even if the urethrocystography is a methodic of first instance, the urethral ultrasonography is efficacious in follow up of urethral injury, particularly in the study of anterior urethra.

[Echographic characteristics of calcifying fibrous pseudotumor of the epididymis].

Calcifying fibrous pseudotumor of epididymis is a rare neoplasia. The A.A. report echographical aspects about two clinical acses examined in 1993. Peculiar aspects of tumour are characterized by acoustic obstruction of the fibrous tissue and contextual iperechogenic spots, so to stimulate a calcific pseudocapsula. The A.A. revalue the echographical images after surgical exploration and discuss about differential diagnosis with TBC.

[Echo-Doppler evaluation of the renal arterial flow in hepatic cirrhosis].

In liver cirrhosis the sodium retention depends on a decreased renal perfusion by arteriolar vasoconstriction. To evaluate the usefulness of echo-Doppler in detecting such hemodynamic impairment, we studied 16 cirrhotic patients and 16 healthy subjects as control group. We measured Pulsatility Index (P.I.) and Resistivity Index (R.I.). Both parameters resulted to be statistically higher in cirrhotic patients than in controls; moreover they resulted to be higher in cirrhotics with ascites than in those without. Therefore echo-Doppler can detect intraparenchymal renal vasoconstriction in cirrhosis, this impaired perfusion is already evident before ascites formation.

[Diagnostic yield in rhino-sinusal inflammatory pathology: comparison of projective radiology, CT and MR].

In everyday practice, the radiologist is concerned with the diagnosis of inflammatory conditions of the nose and paranasal sinuses. This paper was aimed at evaluating and comparing the diagnostic efficacy of the main diagnostic imaging procedures currently available. Fifty-six patients were studied: 25 with computed radiography (CR) and CT, 21 with CR and MRI (0.22 T resistive magnet), and 10 with CR, CT, and MRI. From the diagnostic point of view, the conventional-like CR image was assumed as analog to the conventional radiographic (RX) one on the basis of previous personal experience. The following elements were separately considered for RX, CR, CT, and MRI: anatomical structure identificability, spatial resolution, dosimetry, time consumption, diagnostic results, and economics. A global performance index was calculated (RX less than 1; CR = 1; MRI ranging 1.2-2.2; CT = 7.3). CR was superior to RX, from both a diagnostic and a dosimetric point of view, but buying the equipment is nowadays expensive. CT and MRI were superior to both RX and CR in the diagnosis of inflammatory conditions of the nose and paranasal sinuses. When an inflammatory condition is unquestionable, MRI is more accurate than CT, but the latter (thanks to its optimal documentation of both bony walls and soft tissues) is superior to MRI in the differential diagnosis of a generic disease of the nose and paranasal sinuses--that is, when the inflammatory nature is questionable. MRI limitations were poor visualization of bone walls, high cost, and poor access. Thus, CT emerged as the technique of choice, thanks to its diagnostic results, easy access and low cost, with a negligible radiation dose to patients.

[Stress urinary incontinence in women: magnetic resonance assessment].

The preoperative radiologic study of female stress urinary incontinence is still incomplete and often not well tolerated. MRI is becoming a major diagnostic tool for pelvis assessment also thanks to its allowing dynamic studies. Therefore, MRI was used for the static and dynamic assessment of the pelvic floor, which is compromised in stress incontinence, in a series of 21 patients. Dynamic studies were reliable in all but two cases. Our MRI technique demonstrated anatomical and functional stress urinary incontinence alterations, such as the increased distance between urethra and pubic symphysis (16 patients), vaginal changes (7 patients), levator ani muscle changes (9 patients) and urethropelvic ligaments changes (9 patients). The functional changes caused by pelvic floor collapse were observed in all the patients with reliable dynamic studies, i.e., the posterior urethrovesical angle was increased and the pelvic floor excessively lowered during pelvic strain. Our preliminary results suggest that MRI can play a major role in the preoperative assessment of stress urinary incontinence, notwithstanding the fact that the exam is performed with the patient supine and therefore with no gravity.
