Comparative Study
Interosseous ligament tears of the wrist: comparison of multi-detector row CT arthrography and MR imaging.
To compare the accuracy of multi-detector row computed tomographic (CT) arthrography and magnetic resonance (MR) imaging in depicting tears of dorsal, central, and palmar segments of scapholunate (SL) and lunotriquetral (LT) ligaments in cadavers. ⋯ Performance in depiction of palmar and central segment tears of SL and LT ligaments is almost equal for multi-detector row CT arthrography and MR imaging, with much higher interobserver reliability for CT arthrography. CT arthrography is significantly superior to MR imaging in the detection of dorsal segment tears of SL and LT ligaments.

To evaluate retrospectively the accuracy of multi-detector row computed tomography (CT) in the assessment of serosal invasion in patients with gastric cancer. ⋯ Multi-detector row CT scanning of patients with gastric cancer gave 93% accuracy in the assessment of serosal invasion in patients with gastric cancer.

To determine factors associated with research productivity among all university radiology departments in the United States. ⋯ NIH funding, resident program size, and fellow characteristics are significantly associated with academic research output.

To retrospectively assess the importance and imaging appearance of small (< or = 20 mm in diameter) hepatic arterial phase-enhancing (HAPE) lesions that are occult during portal and/or equilibrium phases and at unenhanced T1- and T2-weighted magnetic resonance (MR) imaging and to determine the gross pathologic diagnosis with whole-liver explant comparison. ⋯ The majority (93%) of HAPE-only lesions that are occult at T2-weighted and portal and/or equilibrium phase MR imaging are nonneoplastic, even in patients with pathologically proved HCC.

To retrospectively evaluate the frequency of blunt cerebrovascular injury (BCVI) in patients with multiple trauma and to retrospectively compare the diagnostic accuracy of duplex Doppler ultrasonography (US) and computed tomographic (CT) angiography by using clinical follow-up and subsequent imaging as reference standards. ⋯ Injuries to the cervical arteries among blunt trauma patients are more common than previously reported. Duplex Doppler US has inadequate sensitivity to help rule out this condition. The notable morbidity with missed dissections warrants routine contrast material-enhanced studies of the carotid and vertebral vessels if patients are scheduled for CT of the cervical spine.
