Comparative Study
Arterial spin-labeling MR imaging in moyamoya disease compared with SPECT imaging.
Arterial spin-labeling (ASL) is a noninvasive magnetic resonance (MR) imaging method used to obtain brain perfusion information on various cerebrovascular diseases. We retrospectively compared the use of ASL-MRI and single-photon emission CT (SPECT) imaging to determine absolute cerebral blood flow (CBF) in moyamoya disease. ⋯ Although the ASL-value was lower than the rest-IMP-value, the significant relationship between the ASL-value and the rest-IMP-value may suggest that perfusion imaging by ASL-MRI could be used to recognize the condition of brain perfusion. In particular, the stronger correlation coefficient between the ASL-value and ACZ-IMP-value might suggest that perfusion imaging by ASL-MRI could show the potentially dangerous zone for ischemia.

To assess the role of multidetector CT angiography (MDCTA) in the diagnosis of acute mesenteric ischemia (AMI) and to compare the diagnostic utility of axial images with reconstructed images. ⋯ MDCTA is an effective non-invasive modality for the diagnosis of mesenteric ischemia.

The aim of this study was to reveal the relationship between intratumoral uptake of gadoliniumethoxylbenzyldiethylenetriaminepentaacetic acid (Gd-EOB-DTPA) of hepatocellular carcinoma (HCC) in the hepatobiliary phase and pathological features. ⋯ The area of Gd-EOB-DTPA uptake does not always match the greenish part, but HCC with uptake of Gd-EOB-DTPA significantly correlated with green HCC.

To evaluate the role, efficacy and safety of pelvic embolization in the management of severe postpartum hemorrhage in women with placenta accreta, increta or percreta. ⋯ In women with severe postpartum hemorrhage due to placenta accreta, increta or percreta, pelvic embolization is effective for stopping the bleeding in most cases, thus allowing uterine conservation and future fertility. Further studies, however, should be done to evaluate the potential of pelvic embolization in women with placenta percreta with bladder involvement.

The embolic agents currently used for the treatment of AVMs are n-butyl cyanoacrylate (NBCA) and ethylene-vinyl alcohol copolymer (ONYX). The purpose of this study was to examine the overall NBCA and ONYX embolization-related complication rate. ⋯ Embolization of brain AVMs is safe, 95.9% of patients had excellent or good outcomes at discharge after AVM embolization using liquid embolic agents, with a complication rate of 4.8%. ONYX embolization was not associated a higher rate of complications comparing with NBCA embolization.
