Notes: Abstract. Vaginal arteriovenous malformations (AVMs), although rare, can lead to life-threatening complications. We report the first case of a vaginal AVM whose diagnosis and follow-up were performed by magnetic resonance imaging (MRI). MRI findings of the AVM are the blood flow-related features within the tumor, such as the phase-shift artifact, paradoxical enhancement, and flow voids.

Notes: Abstract Background: To determine the optimal phases of dynamic computed tomography (CT) for detecting hepatocellular carcinoma (HCC). Methods: Fifty-two patients with 85 HCC nodules were examined by means of unenhanced and triple-phase CT images of the whole liver. The time for obtaining the arterial-phase images was 25–55 s after intravenous bolus injection of contrast material, the time for obtaining the portal venous-phase images was 65–100 s, and the time for obtaining late-phase images was 145 s to 4 min. Detectability of the HCC nodules for all phases was statistically compared. Results: The detection rates for the arterial- and late-phase images were significantly higher than for the unenhanced and portal venous-phase images (p 〈 0.01). The combination of arterial- and late-phase images showed the same number of HCC nodules in the same number of patients as did the combination of unenhanced and triple-phase images. Conclusion: The combination of the arterial- and late-phase imagings was best for detecting HCC nodules.

Topics: Medicine

Notes: Abstract. We reviewed the MR images and pathologic findings of five cases of primary vaginal neoplasms of non-squamous origin. Histologic types consisted one case each of adenocarcinoma, adenosarcoma, melanoma, lymphoma, and neurilemoma. Magnetic resonance imaging was found useful for evaluating the type and the extension of vaginal tumors.
