BACKGROUND Coincidence imaging of low-abundance yttrium-90 (90Y) internal pair production by positron emission tomography with integrated computed tomography (PET/CT) achieves high-resolution imaging of post-radioembolization microsphere biodistribution. Part 2 analyzes tumor and non-target tissue dose-response by 90Y PET quantification and evaluates the(More)
BACKGROUND Yttrium-90 (90Y) positron emission tomography with integrated computed tomography (PET/CT) represents a technological leap from 90Y bremsstrahlung single-photon emission computed tomography with integrated computed tomography (SPECT/CT) by coincidence imaging of low abundance internal pair production. Encouraged by favorable early experiences, we(More)
Endochondral pseudocyst of the auricle is an uncommon condition that affects predominantly Chinese males, with many reports studying this condition in homogenous Chinese populations. There have been few large-scale reports describing the features of this disease among the other Asian groups. In one of the largest series described to date, we report the(More)
STUDY TYPE Therapy (case series). LEVEL OF EVIDENCE 4. OBJECTIVE To present our institution's experience of selective embolization of renal angiomyolipomas with alcohol and the long-term follow up data. PATIENTS AND METHODS This retrospective study included 34 patients treated between October 1997 and October 2007 (29 women and five men, mean age 44(More)
This study reviews our experience with dynamic computed tomographic angiography (CTA) as an imaging modality in the evaluation of popliteal artery entrapment syndrome (PAES). Eight patients with surgically proven PAES were included in this study. Dynamic CTA studies performed with the feet in neutral and plantar flexed positions were reviewed for the(More)
To assess the efficacy of the Wallstent endoprosthesis in malignant tracheobronchial obstruction. Seven patients with irresectable carcinoma of the bronchus were treated with nine Wallstent endoprostheses. The procedures were performed under endoscopic and fluoroscopic guidance. Wallstent endoprostheses ranging from 8–16 mm in diameter and 26–49 mm in(More)
AIM To identify the clinical predictors and assist surgeons in their clinical management of obstructive sleep apnoea (OSA) - a prospective study with a new approach to analyse the static and dynamic upper airway morphology between patients with OSA and normal subjects. To introduce a new method of assessment for surgical outcome. MATERIALS AND METHODS(More)
The recent epidemic of severe acute respiratory syndrome caught many by surprise. Hitherto, infection control has not been in the forefront of radiological practice. Many interventional radiology (IR) services are therefore not equipped to deal with such a disease. In this review, we share our experience from the interventional radiologist’s perspective,(More)
UNLABELLED The aim of this paper was to study the efficacy, side effects and complications of radiofrequency (RF) ablation of primary and metastatic liver malignancies. MATERIALS AND METHODS We retrospectively reviewed 57 patients (39 men, 18 women; mean age, 63 years; age range, 44 to 83 years) who underwent RF ablation for liver malignancies from(More)
OBJECTIVE To review the microbiology of open tympanomastoid cavities in patients who underwent revision surgery due to chronic instability. METHODS This paper describes a retrospective chart review of surgical revision cases of chronically unstable open mastoid cavities. Patient records from 2000 to 2010 were reviewed for the type of organism cultured,(More)
