The US and CT findings in a case of afferent loop obstruction after total gastrectomy are reported. A U-shaped fluid filled tubular structure crossing the midline between the abdominal aorta and the superior mesenteric artery (SMA) is a characteristic US and CT image of an afferent loop obstruction. CT is helpful to recognize the bowel wall and to demonstrate its relationship with the biliary system. Its vague clinical picture and confusing laboratory findings may mimic pseudocysts.

Ultrasound is currently the primary imaging modality for the assessment of scrotal disease. In acute pathology, colour Doppler adds further confirmation about blood flow to the testicles and surrounding structures. MR is emerging as a powerful tool to image the scrotum. Compared with sonography, MR has a wider field of view and a greater tissue contrast. The current status of MR imaging and its role in the evaluation and local staging of testicular tumors is evaluated in this retrospective study. MR is able to differentiate seminomatous from non-seminomatous tumors in nearly all cases. However, stromal tumors (e.g. Leydig cell tumors) cannot be differentiated from seminomatous tumors, and some benign lesions, as an intratesticular hematoma, cannot be differentiated from non-seminomatous tumors. Microscopic extension in or beyond the tunica albuginea cannot be evaluated.

Fifty patients with newly diagnosed, untreated intracranial tumors were examined with 1H nuclear magnetic resonance single-volume spectroscopy (MRS) using a 1.5 T whole-body MR system. Prior to the MRS, contrast enhanced MR and/or CT imaging studies were carried out. Histological verification was obtained in all patients except one. All tumor spectra revealed distinct abnormalities as compared with the normal brain spectra. Although most meningiomas showed a rather characteristic spectral pattern, generally features specific for the various tumor types were not observed. For instance, though a strong lactic acid signal was seen in most malignant tumors, this signal was also evident in five benign neoplasms.
