Sarcopenia is associated with increased waitlist mortality, but a standard definition is lacking. In this retrospective study, we sought to determine the optimal definition of sarcopenia in end-stage liver disease (ESLD) patients awaiting LT. Included were 396 patients newly listed for LT in 2012 at five North American transplant centers. All CT scans were read by two individuals with inter-observer correlation of 98%. Using image analysis software, the total cross-sectional area (cm(2) ) of abdominal skeletal muscle at L3 was measured...

BACKGROUND/OBJECTIVES: Hyperlipasemia is frequently encountered in patients in the intensive care unit (ICU). The degree to which it should be valued in making the diagnosis of acute pancreatitis (AP) in critically ill patients remains uncertain. We sought to determine the diagnostic accuracy of hyperlipasemia and the optimal lipase cutoff for diagnosing AP in critically ill patients. METHODS: Four hundred and seventeen ICU patients with hyperlipasemia, defined as lipase greater than three times the upper limit of normal from 2009 to 2012 were retrospectively identified...

N Patel, A J King, D J Breen
The role of minimally invasive, locoregional therapies in cancer is increasingly driven by the detection of small asymptomatic disease either incidentally or under surveillance for a known primary malignancy. Percutaneous image-guided ablation has become established as a parenchyma-sparing tool in the management of small volume primary and metastatic disease in the liver as well as solitary renal masses. As ablation is non-extirpative, post-ablation imaging is critical for the assessment of treatment completion, recurrence, and complications...

The increased use of abdominal imaging has led to a major increase in small renal tumors incidence particularly in the elderly population. Their management is evolving with the development of percutaneous ablation, particularly radiofrequency ablation, cryoablation, and microwave ablation. The typical indications that must be validated by a multidisciplinary committee include solid tumors less than 3cm in patients with multiple comorbidity factors (including age), contraindications to surgery, hereditary renal cancer, bilateral renal tumors, solitary kidney, pre-existing chronic kidney disease, or at high risk of predialysis renal function after partial nephrectomy...

A 10-year-old male neutered mixed breed dog was evaluated for cervical hyperesthesia and tetraparesis. Magnetic resonance imaging of the brain and cervical spinal cord identified an extradural compressive lesion over the body of C2 caused by marked dilation of the vertebral venous sinuses. Following intravenous contrast administration both vertebral sinuses had heterogeneous contrast enhancement consistent with incomplete thrombi formation. An abdominal ultrasound also showed a distal aortic thrombus. A definitive cause for the thrombi formation was not identified, but the patient had several predisposing factors which may have contributed...

Postmortem magnetic resonance imaging (MRI) is emerging as a valuable tool to accompany traditional autopsy and has potential for use in cases when traditional autopsy is not possible. This case report will review the use of postmortem MRI with limited tissue sampling to differentiate between metastatic neuroblastoma and hepatoblastoma which could not be clearly differentiated with prenatal ultrasound, prenatal MRI, or emergent postnatal ultrasound. The mother presented to our institution at 27 weeks gestation after an obstetric ultrasound at her obstetrician's office identified a large abdominal mass...

Primary malignant tumors of the diaphragm are rare, and primary liposarcoma of the diaphragm is extremely rare. The role of imaging is description of the anatomic relationships of the tumor as well as a suggestion of histologic diagnosis based on the presence of fatty and/or nonfatty components.

Although percutaneous endoscopic gastrostomy (PEG) tube placement is a common and safe procedure to provide enteral feeding, some patients develop complications. The aim of this study was to identify risk factors for the development of post-PEG complications. We hypothesized that patients with low albumin, diabetes, higher body mass index (BMI), thicker abdominal walls, or psychomotor agitation would have more complications. A 2-year retrospective review was performed on patients who received a PEG tube at a single institution...

In a variety of injuries and illnesses, internal organs in the abdominal and pelvic regions, in particular liver, may be compromised. In the current practice, CT scans of liver are visually inspected to investigate the integrity of the organ. However, the size and complexity of the CT images limits the reliability of visual inspection to accurately assess the health of liver. Computer-aided image analysis can create fast and quantitative assessment of liver from the CT, in particular in the environments where access to skilled radiologists may be limited...

Automatic calcification detection in abdominal aorta consists of a set of computer vision techniques to quantify the amount of calcium that is found around this artery. Knowing that information, it is possible to perform statistical studies that relate vascular diseases with the presence of calcium in these structures. To facilitate the detection in CT images, a contrast is usually injected into the circulatory system of the patients to distinguish the aorta from other body tissues and organs. This contrast increases the absorption of X-rays by human blood, making it easier the measurement of calcifications...

Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of a non-pituitary ACTH-secreting tumor leading to Cushing's syndrome. Only a few cases have been reported previously as causing ectopic ACTH related to paraganglioma. Herein, we present a case of Cushing's syndrome, in who was proved to be attributable to an ACTH-secreting renal malignant paraganglioma. A 40-year-old woman presented with a five-month history of newly diagnosed hypertension and diabetes, weakness, hyperpigmentation, oligomenorrhea, hirsutism, and acneiform lesions...

BACKGROUND/OBJECTIVES: Delayed treatment failure occurs in a significant proportion of inflammatory bowel disease (IBD) patients treated with tumor necrosis factor-alpha (TNF) antagonists. Identification of predictors of loss of response (LOR) may help to optimize therapy. We sought to determine whether body composition parameters at the commencement of anti-TNF therapy were associated with earlier treatment failure. SUBJECTS/METHODS: A retrospective cohort study was performed on 68 patients who had undergone cross-sectional abdominal imaging coincident with the commencement of anti-TNF drugs...
