PURPOSE: Low-dose non-enhanced computed tomography (LDCT) has been shown to provide low radiation exposure with proper diagnostic accuracy compared to standard dose non-enhanced computed tomography (SDCT) in patients with renal colic. The goal of our study is to estimate the accuracy of LDCT and SDCT interpretation by emergency medicine residents who primarily treated patients with renal colic. MATERIALS AND METHODS: Thirty sample images of both LDCT and SDCT from renal colic patients were extracted from January 2013 to December 2015 in a tertiary teaching hospital...

A subset of benign (WHO grade I) skull base meningiomas show early progression/recurrence (P/R) in the first years after surgical resection. Besides, complete surgical resection may be difficult to achieve safely in skull base meningiomas due to complex neurovascular structures. The one main challenge in the treatment of skull base meningiomas is to determine factors that correlate with P/R. We retrospectively investigated the preoperative CT and MR imaging features for the prediction of P/R in skull base meningiomas, with emphasis on quantitative ADC values...

BACKGROUND: Dynamic CT angiography (dCTA) augments traditional CTA with temporal resolution and has been demonstrated to influence operative planning in skull base surgery. METHODS: Three hundred twenty-five dynamic CTA cases from a single institution were reviewed for indication of study, findings, and comparison to other modalities of imaging. RESULTS: The most frequent application of dCTA was pre-operative surgical planning (59.4%); resection of skull base tumors represented the majority of these pre-operative studies (93...

Timing of fusion of the spheno-occipital synchondrosis (SOS) is correlated with age. Previous research, however, has demonstrated variation in the timing of closure among different global populations. The present study aims to quantify the timing of SOS fusion in Malaysian individuals as visualised in multi-detector computed tomography (CT) scans and to thereafter formulate age estimation models based on fusion status. Anonymised cranial CT scans of 336 males and 164 females, aged 5-25 years, were acquired from the National Institute of Forensic Medicine, Hospital Kuala Lumpur and Department of Diagnostic Imaging, Hospital Sultanah Aminah...

Computed tomography (CT) with contrast plays an important role as a clinical diagnostic tool but still has a limited diagnostic range. In this work, we developed a novel injectable iodine-based small molecule CT contrast agent, even can be used for bile duct diagnostics. The bile duct diagnosable CT contrast agent (BDICA) is synthesized with 5-amino-2,4,6-triiodoisophthaloyl dichloride (ATIPC), tromethamine and lactobionic acid (LBA) for asialoglycoprotein receptor (ASGPR) targeted delivery via receptor-mediated endocytosis and transport to the bile canaliculi...

Pancreas disease (PD) caused by salmonid alphavirus (SAV) is the most serious viral disease in Norwegian aquaculture. Study of the immune response to SAV will aid preventative measures including vaccine development. The innate immune response was studied in Atlantic salmon infected by either bath immersion (BI) or by intra-muscular (i.m.) injection (IM) with SAV subtype 3, two and nine weeks after seawater transfer (Phases A and B respectively). Phase A results have been previously published (Moore et al., 2017) and Phase B results are presented here together with a comparison of results achieved in Phase A...

Bronchial granular cell tumor is a rare tumor. A 39-year-old non-smoker woman was admitted to our hospital with back pain. Chest CT and bronchoscopy scan revealed a 10mm endobronchial tumor arising from the membrane near the second carina. The tumor was excised inclusive of the right second carina containing the extraluminally invaded endobronchial mass and was diagnosed as a granular cell tumor. The postoperative course was uneventful and the patient was well without signs of recurrence for 3 year follow-up...

OBJECTIVES: The lower limit of the membranous septum (MS) is considered an anatomic landmark for the emergence of the Bundle of His into the left ventricle. Computed tomography (CT) assessment of MS anatomy may provide useful information about the risk of conduction abnormalities following transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: The study included 102 consecutive patients undergoing TAVR with the Edwards Sapien 3 (S3) valve. Using pre-TAVR CT and post-procedure angiography we evaluated for the presence of calcium in the left ventricular outflow tract (LVOT), calcium depth (CD), implantation depth (ID) and MS length...

INTRODUCTION: Endoscopic therapy remains the cornerstone of hemostasis for gastrointestinal bleeding. In situations where hemostasis cannot be achieved via endoscopic or radiological methods, surgery is necessary. Traditional open surgery for bleeding gastric ulcers can be very morbid and unsuitable especially in hemodynamically unstable patients in extremis. We describe a minimally invasive, transgastric approach for underrunning and closure of Cameron ulcers. METHODS: Our patient is a 75-year-old Chinese lady, who presented to the emergency department with fresh melena...
