WebThe CT and MRI findings in adnexal torsion with fibroma include tube thickening, ascites, deviation to the twisted side, hemorrhage in the thickened tube, and torsion knot. ... The finding of a high-signal-intensity area in the periphery of the mass on T1-weighted imaging is helpful in diagnosis of hemorrhagic infarction of fibroma (Figs. 7A ... WebAbnormalities in white matter, known as lesions, are most often seen as bright areas or spots on MRI scans of the brain. Very often the lesions themselves don't cause any noticeable problems.

WebOct 14, 2024 · Creating T1 weighted images requires a short time to echo (TE) and repetition times (TR). These refer to the duration between the radiofrequency pulse’s delivery and the capture of the echo signal, and the measured time between pulse sequences applied to an area, respectively. On the other hand, T2 weighted images use … WebThree-dimensional ultrasound mosaicing can increase image quality and expand the field of view. However, limited work has been done applying these compounded approaches for cardiac procedures focused on the mitral valve. For procedures targeting the mitral valve, transesophageal echocardiography (TEE) is the primary imaging modality used as it … WebIn 50 patients with temporal-lobe epilepsy, CT and MR findings were compared. Axial CT scans were obtained before and after administration of contrast material. Coronal MR imaging was carried out with two spin-echo (SE) sequences with a repetition time of 1600 msec and echo times of 35 or 70 msec (SE 1600/35, SE 1600/70).
