    Notes: Abstract. Background: To demonstrate the radiologic–pathologic correlation of adenomyomatosis of gallbladder (GBA) and emphasize the role of high-resolution real-time ultrasound (RTUS) in the diagnosis of GBA. Methods: Ten (four male and six female, mean age = 49 years) patients with proven GBA (three diffuse, three segmental, and four fundal) diagnosed by histopathology or confirmed by oral cholecystography (OCG) were reviewed. Radiologic studies included OCG (n = 8), RTUS (n = 8), and computed tomography (CT; n = 4). Six patients subsequently underwent cholecystectomy. Results: Histopathologic correlation between pathologic specimens and OCG, RTUS, and CT was possible in six patients. The diagnostic criteria with ultrasound included numerous tiny intramural cysts containing echogenic foci with reverberation artifacts and associated segmental or diffuse gallbladder wall thickening. OCG with fatty meal demonstrated intramural diverticula. Localized fundal GBA was better visualized on RTUS and CT scan than on OCG. Conclusion: Accurate diagnosis of GBA may be made by either OCG or high-resolution RTUS preoperatively. CT scan may used as an alternative method to help make the diagnosis in equivocal cases.

    Notes: Abstract Background: The purpose of this study was to compare the performance of in-phase and out-of-phase gradient recalled echo (GRE) pulse sequences on paramagnetic contrast-enhanced magnetic resonance (MR) imaging of malignant liver lesions. Methods: Fifty patients (27 women, 23 men; mean age = 50 ± 27 years) with known or suspected focal liver lesions, nine of whom had a fatty liver, were examined at 1.5 T before and 60 min after injection of gadobenate dimeglumine at a dose of 0.05 or 0.1 mmol/kg using two GRE techniques: echo time of 2.3 ms (out-of-phase) or 4.6 ms (in-phase). Liver signal-to-noise ratio (SNR) and lesion–liver contrast-to-noise ratio (CNR) were calculated. Results: In patients with a nonfatty liver, liver SNR increased from 26 ± 9 to 41 ± 17 on in-phase images and from 28 ± 8 to 45 ± 14 on out-of-phase images. In patients with a fatty liver, in-phase images provided significantly higher (p 〈 0.01) liver SNR than did out-of-phase images predose (34 ± 8 on in-phase vs. 21 ± 8 on out-of-phase) and postdose (44 ± 13 on in-phase vs. 33 ± 14 on out-of-phase). In patients with a nonfatty liver, lesion–liver CNR was similar on in-phase and out-of-phase images, predose and postdose. In patients with fatty liver, lesion–liver CNR was significantly (p 〈 0.01) lower on out-of-phase images on predose and postdose images. Conclusion: In-phase GRE imaging is recommended for imaging focal liver lesions on paramagnetic contrast-enhanced MR imaging in patients with fatty infiltration of the liver.
