AIM: Coronary artery calcification (CAC) score on computed tomography (CT) or vascular calcification (VC) scores on plain radiographs are associated with cardiovascular events and fracture. We investigated which VC score among several VC scores on plain radiographs is predictor of CAC, and whether VC scores are related with bone mineral density (BMD) in dialysis patients. METHODS: We checked several plain radiographs (hands and pelvis [HP], feet and lateral lumbar spine), BMD and multidetector CT scans of 55 patients maintaining dialysis in this cross-sectional study...

INTRODUCTION: Gastric volvulus (GV) is a rare and life threatening condition if not treated promptly or wrongly diagnosed. The main complication of gastric volvulus is foregut obstruction. The extreme rotation can cut off blood supply to the stomach and even distal organs, which can lead to ischemia and necrosis of the affected area. PRESENTATION OF CASE: We report a case of a 41yo female that complained of severe abdominal pain, nausea and vomiting for approximately 3days after eating a large meal...

A 65-year-old female presented with recurrent urinary tract infections. A computed tomography of the abdomen and pelvis shows a dilated and malrotated right renal pelvis consistent with a ureteropelvic junction (UPJ) obstruction as well as multiple renal arteries arising from the aorta. A computed tomography angiography (CTA) revealed five separate renal arteries originating from the aorta with a single renal artery crossing over and obstructing the right renal pelvis. On Lasix renogram, the affected kidney contributes 45% of total renal function...

Regular imaging is used throughout image guided radiation therapy (IGRT) to improve treatment delivery. In order for treatment procedures to be optimized, the doses delivered by imaging exposures should be taken into account. CT dosimetry methods based on the CT dose index (CTDI), measured with a 100 mm long pencil ionization chamber (CTDI<sub>100</sub>) in standard phantoms, are not designed for the cone beam CT (CBCT) imaging systems used in radiotherapy, therefore a modified version has been proposed for CBCT by the International Electrotechnical Commission (CTDI<sub>IEC</sub>)...

Muscle activation has been demonstrated to influence impact dynamics during scenarios including running, automotive impacts, and head impacts. This study investigated the effects of targeted muscle activation magnitude on impact dynamics during low energy falls on the hip with human volunteers. Fifteen university-aged participants (eight females, seven males) underwent 12 lateral pelvis release trials. Half of the trials were muscle-'relaxed'; in the remaining 'contracted' trials participants isometrically contracted their gluteus medius to 20-30% of maximal voluntary contraction before the drop was initiated onto a force plate...

BACKGROUND: Few studies have compared the biomechanical outcomes of different surgical approaches for hip arthroplasty. The purpose of this study was to compare hip, pelvic, and trunk kinematics and kinetics between individuals who underwent a posterior or anterolateral approach. METHODS: Forty-five individuals between 40 and 80 years old underwent motion analysis during overground gait prior to hip arthroplasty and 3 months after surgery. Walking speed, hip flexion angle, hip extension angle, adduction angle and moment, trunk angle, trunk lean, and pelvis drop were compared between approaches...

BACKGROUND: Metastases to the bone are common in cancer patients, and it has been estimated that up to 50% of patients with pelvic bone metastases will not achieve adequate pain control with medications alone. This has led to a paradigm shift over recent years towards the use and development of minimally invasive image-guided treatment options for palliation of bony metastases. Despite these developments, large metastatic lesions are still often considered to be "hopeless cases" that would garner little to no benefit from image-guided intervention...

Ganglioneuromas are a very rare benign neural tumor, commonly derived from the ganglia of the sympathetic system, and are composed of mature Schwann cells, ganglion cells, and nerve fibres. They may arise anywhere from the base of the skull to the pelvis along the paravertebral sympathetic plexus. We report a rare case of synchronous ganglioneuroma and schwannoma, mistaken for carotid body tumor. The coexistence of these two entities in head and neck region is very rare.

This study examines the ability of commonly used supervised learning techniques to classify the execution of a maximum effort change of direction task into predefined movement pattern as well as the influence of fuzzy executions and the impact of selected features (e.g. peak knee flexion) towards classification accuracy. The experiment utilized kinematic and kinetic data from 323 male subjects with chronic athletic groin pain. All subjects undertook a biomechanical assessment and had been divided previously into 3 different movement strategies in an earlier paper...

Although delayed-time-point imaging is expected to improve the results of [F]-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT), how examinees will benefit from dual-time-point imaging versus initial-time-point imaging alone, remains unclear. This study investigated the role of delayed-time-point imaging in improving the results of abdominal and pelvic cancer screening using FDG-PET/CT.This retrospective review included 3131 screening results (average subject age: 55.5 years, range: 40-88 years)...

Here we report a case of sclerosing mesenteritis that we diagnosed with needle biopsy under the guidance of computed tomography (CT) and ultrasound (US) observation. An 82-year-old woman presented with appetite loss, weight loss and epigastric pain. CT of the abdomen and pelvis revealed increased density of the mesentery adjacent to the small bowel and enlarged lymph nodes. Sclerosing mesenteritis was suspected, but malignancies, such as lymphoma, were also considered. We performed CT and US-guided needle biopsy with the coaxial technique...

INTRODUCTION: More than half of all traumatic deaths happen in prehospital settings. Until now, there have been no long-term studies examining the actual additive treatment during trauma-associated cardiopulmonary resuscitation (tCPR), including pleural decompression, pericardiocentesis, tourniquets and external stabilization of the pelvis. The present cohort study evaluated forensic autopsy reports of trauma deaths occurring at the scene with respect to additive actions in preclinical tCPR as well as the potentially preventable nature of the individual death cases...
