Duplication of the superficial femoral artery diagnosed primarily on the basis of color Doppler ultrasonography

Variations of the lower extremity venous system are common, and radiologists may frequently be confronted with such variations during daily clinical practice. However, variations in the arterial system of the lower extremity are extremely rare. The profunda femoris artery and arteries of the cruris are mainly subject to variation.(1,2

Diffusion tensor imaging of the normal prostate at 3 Tesla

The aim of this study was to assess the feasibility of diffusion tensor imaging (DTI) of the prostate and to determine normative fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of healthy prostate with a 3-Tesla magnetic resonance imaging (MRI) system. Thirty volunteers with a mean age of 28 (25-35) years were scanned with a 3-Tesla MRI (Intera Achieva; Philips, The Netherlands) system using a six-channel phased array coil. Initially, T2-weighted turbo spin-echo (TSE) axial images of the prostate were obtained. In two subjects, a millimetric hypointense signal change was detected in the peripheral zones on T2-weighted TSE images. These two subjects were excluded from the study. DTI with single-shot echo-planar imaging (ssEPI) was performed in the remaining 28 subjects. ADC and FA values were measured using the manufacturer supplied software by positioning 9-pixel ROIs on each zone. Differences between parameters of the central and peripheral zones were assessed. Mean ADC value of the central (1.220 +/- 0.271 x 10(-3) mm(2)/s) was found to be significantly lower when compared with the peripheral gland (1.610 +/- 0.347 x 10(-3) mm(2)/s) (P < 0.01). Mean FA of the central gland was significantly higher (0.26), compared with the peripheral gland (0.16) (P < 0.01). This study shows the feasibility of prostate DTI with a 3-Tesla MR system and the normative FA and ADC values of peripheral and central zones of the normal prostate. The results are compatible with the microstructural organization of the gland

Vasculopathic changes in the cerebral arterial system with neurobrucellosis

Brucellosis is a zoonotic disease characterized by multisystem involvement. Nervous system involvement is rare, with a reported incidence of 3%-13%. Brucellosis can also be manifested in the form of vasculopathy. Cerebral vasculopathy due to brucellosis is a very rare entity, with only a few cases reported in the literature. We present a patient with neurobrucellosis who had involvement of cerebral vasculature demonstrated by angiography

Testicular Size and Vascular Resistance Before and After Hydrocelectomy

OBJECTIVE. We sought to determine whether there is an association between hydroceles and testicular size and vascular resistance
