Ultrasound-guided aspiration of wrist ganglions: a follow-up survey of patient satisfaction and outcomes.
CONCLUSION: US-guided aspiration is a safe and potentially effective treatment for ganglion cysts of the wrist, with high patient satisfaction. US-guided aspiration may be particularly advantageous for volar ganglion cysts, and in patients who are poor surgical candidates.

Peroneal tendon pathology evaluation using the oblique sagittal plane in ankle MR imaging.
Abstract BACKGROUND: Because peroneal tendons course from the lateral side of the proximal fibula through the posterior side of the distal fibula, correct diagnosis of the tendon pathology on an orthogonal sagittal plane can be difficult. PURPOSE: To evaluate the diagnostic usefulness of oblique sagittal imaging (peroneal view) for evaluation of peroneal tendon pathology. MATERIAL AND METHODS: This retrospective study included 69 patients at our institution who underwent routine ankle magnetic resonance imaging (MRI) using the peroneal view. Twenty-three patients underwent arthroscopy. Anatomic identific...

Imaging of biliary complications in recipients of right-lobe living donor liver transplantation.
Abstract Right-lobe living donor liver transplantation (RL-LDLT) is a common method devised in order to fulfill the demands of donor organ shortage in adult patients with end-stage liver diseases. However, biliary complications remain as the "Achilles' heel" of RL-LDLT, with wide variety of incidence among transplantation centers. Patients with biliary complications after RL-LDLT may have similar clinical presentations to those with other causes of graft dysfunction. Therefore, radiological evaluation plays a key role for differential diagnosis of such complications. In this article, we discuss the vario...
