    Gallbladder perforation: Comparison of US findings with CT (1994)
    Springer
    Abdominal imaging 19 (1994), S. 239-242

    Notes: Abstract We compared the ultrasound (US) findings of gallbladder (GB) perforation with computed tomography (CT) in 13 patients with GB perforation confirmed at surgery. The common findings of GB perforation were pericholecystic fluid collection and layering of GB wall on US, pericholecystic fluid collection, streaky omentum or mesentery, and GB wall defect on CT. Pericholecystic fluid collection, layering of GB wall, and cholelithiasis were similarly detected on US or CT. GB wall defect and/or bulging of the GB wall suggested a site of perforation was revealed in five patients (38.5%) on US and nine (69.2%) on CT. CT further disclosed the findings of streaky omentum or mesentery (84.6%). CT was superior to US for diagnosis of GB perforation.

    Notes: Abstract We report three cases of intraperitoneal seeding from hepatoma. Manifestation of intraperitoneal seeding from hepatoma were intraperitoneal masses (N = 2) and peritoneal thickening (N = 1). Main vascular feeder to intraperitoneal masses was omental branches of the gastroduodenal artery and/or the superior mesenteric artery.

    Budd-Chiari syndrome: hepatic venous obstruction by an elevated diaphragm (1999)
    Springer
    Abdominal imaging 24 (1999), S. 267-271

    ISSN: 1432-0509

    Topics: Medicine
    Notes: Abstract We describe two cases of Budd-Chiari syndrome detected by magnetic resonance imaging that resulted from compression of the inferior vena cava by an elevated right hemidiaphragm. Magnetic resonance images demonstrated elevation of the right hemidiaphragm and medial deviation of the inferior vena cava with short segmental narrowing. The hepatic veins and inferior vena cava were patent but discontinuous. Hepatic venous drainage was assisted by multiple large intrahepatic collaterals.

    Hepatic involvement in hypereosinophilic syndrome: value of portal venous phase imaging (1998)

    Notes: Abstract. US, portal venous phase CT, and MRI-CSE (MRI with conventional spin-echo sequence) findings in three cases of hepatic involvement in hypereosinophilic syndrome are presented. These showed varied imaging findings, but portal venous phase CT showed multiple, poorly marginated, and hypodense hepatic lesions in all three cases. The result suggested that portal venous phase CT is the optimal method for depicting hepatic involvement.

    Colonic wall thickening in cirrhotic patients: CT features and its clinical significance (1999)

    Notes: Abstract Background: To evaluate the computed tomographic (CT) features of colonic wall thickening in cirrhotic patients and to determine their prognostic value. Methods: We retrospectively reviewed 28 cirrhotic patients with colonic wall thickening (≥10 mm) on CT. Twenty-six of the 28 patients had hepatocellular carcinoma. The severity of hepatic dysfunction was determined by using the Child–Pugh classification. We analyzed the patterns of bowel wall thickening and degree of portal hypertension on CT and the survival periods after initial CT detection of colonic wall thickening. Results: The involved segment of the colon was diffusely thickened with either scalloped or nodular circumferential configuration. In all patients, the thickened colonic wall enhanced poorly. Although the ascending colon was involved in all patients, the transverse (n= 14) or descending (n= 5) colon was also simultaneously involved. Most patients exhibited an advanced stage of portal hypertension on CT. The median survival period of 25 patients who expired was 34 days, and 21 patients (84%) expired within 3 months. Conclusions: Colonic wall thickening on CT can be used as one of the indicators of poor prognosis in cirrhotic patients. Advanced liver cirrhosis with significantly severe dysfunction is the likely cause of mortality. Therefore, a less aggressive therapeutic approach is recommended if hepatocellular carcinoma is coexistent in these patients.

    Notes: Abstract Background: To evaluate the diagnostic efficacy of fast T2-weighted magnetic resonance (MR) imaging sequences on image quality, hepatic lesion detection, and lesion conspicuity. Methods: Three breath-hold, fast T2-weighted sequences with turbo-spin-echo (TSE), half-Fourier acquisition single-shot TSE (HASTE), and inversion recovery (IR) HASTE techniques were examined for 43 lesions in 20 consecutive patients. Evaluation was performed qualitatively on image quality and lesion detectability and quantitatively on lesion conspicuity by using lesion/liver signal-intensity and contrast-to-noise ratios. Results: Artifacts were significantly less present on the HASTE sequence (p 〈 0.01). Both TSE and HASTE sequences detected 39 lesions (91% each); the IR HASTE sequence detected 37 (86%). IR HASTE sequence showed a significantly higher signal-intensity ratio than did the others (p 〈 0.01). Conclusions: Breath-hold TSE versus breath-hold HASTE or IR HASTE is still the most robust sequence in lesion detection, image quality, and lesion conspicuity. However, the HASTE sequence offers good lesion detection and image quality, and the IR HASTE has a better signal-intensity ratio.

    Use of methylcellulose in small bowel follow-through examination: comparison with conventional series in normal subjects (1998)

    Notes: Abstract. Background: To evaluate and optimize a modified small bowel follow-through examination (SBFT) by using an oral administration of a large amount (600 mL) of methylcellulose after taking a small amount of barium. Methods: Ninety-nine normal subjects underwent modified SBFT with an oral administration of 600 mL of 0.5% methylcellulose after taking 100 mL of 120% or 100, 150, or 200 mL of 70% w/v barium. The transradiancy and distensibility of the bowel and the transit time were compared with those of 39 other normal subjects who underwent conventional SBFT with 500 mL of 70% w/v barium. Results: Except for two subjects who developed diarrhea immediately after examination, no patients complained of acute symptoms, such as abdominal pain or vomiting. Modified SBFT was much superior to conventional series for obtaining good bowel transradiancy and rapid transit time (range = 37–49 min), but bowel distention was not significantly improved. The use of 150 mL of 70% w/v barium was better than the other three modified techniques for achieving good bowel transradiancy, rapid transit time, and less occurrence of flocculation. Conclusion: Modified SBFT is a simple method for easily improving the image quality in terms of bowel transradiancy and transit time.

    Notes: Abstract We report the imaging findings of spiral computed tomography (CT), magnetic resonance (MR) imaging, and MR angiography in a patient with nodular regenerative hyperplasia of the liver associated with Budd–Chiari syndrome. Spiral CT showed multiple enhancing nodules during the hepatic arterial and portal venous phases. MR images showed multiple hyperintense nodules on T1-weighted images and hypointense or isointense nodules on T2-weighted images. MR angiography showed thrombotic occlusion of three hepatic veins, suggesting Budd–Chiari syndrome.
