The purpose of this report is to show the imaging characteristics of saphenous vein graft aneurysms and pseudoaneurysms. Conventional radiographic, CT, and coronary angiography images were reviewed for three patients ranging from 64 to 69 years old who had documented saphenous vein graft aneurysms or pseudoaneurysms. ⋯ Saphenous vein graft aneurysms and pseudoaneurysms appear as paracardiac, hilar, or mediastinal masses on chest radiographs. On CT, the lesions are enhancing tubular mixed-attenuation masses along the heart border. Coronary angiography confirms the graft dilatations. Knowing the imaging characteristics of these entities should lead to their diagnosis and prevent unnecessary complications.

Comparative StudyDetection and segmental location of malignant hepatic tumors: comparison of ferumoxides-enhanced gradient-echo and T2-weighted spin-echo MR imaging.
The aim of our prospective study was to compare the values of ferumoxides-enhanced gradient-echo and T2-weighted spin-echo MR imaging for the detection and segmental location of malignant hepatic tumors. ⋯ In our study, ferumoxides-enhanced gradient-echo imaging was as accurate as T2-weighted spin-echo imaging for revealing malignant hepatic tumors and was superior for showing their segmental location.

Endometrial thickness in tamoxifen-treated patients: correlation with clinical and pathologic findings.
This study was performed to evaluate sonographic measurements of endometrial thickness in postmenopausal breast cancer patients being treated with tamoxifen and to correlate endometrial thickness with pathology, symptoms, and duration of tamoxifen treatment. ⋯ The majority of women being treated with tamoxifen were asymptomatic, but 48% of sonograms revealed an endometrial thickness of 8 mm or more. Endometrial polyps, the most common abnormality, were diagnosed in 33% of biopsies performed for endometrial thickness of 8 mm or more. Endometrial thickness showed no correlation with symptoms, but we found a statistically significant correlation between increased endometrial thickness and duration of tamoxifen treatment that was longer than 5 years.
