Micro cone beam computed tomography for sensitive assessment of radiation-induced late lung toxicity in preclinical models.

CONCLUSION: µCBCT after right lung µIGRT enables the sensitive detection of effects inflicted by relative small dose increments or radio-sensitizers. Our preclinical model therefore facilitates the determination of lung damage exacerbation for the safety assessment of novel RT-drug combinations. PMID: 31146069 [PubMed - as supplied by publisher]

We report a case of a 46-year-old Chinese male who presented with six months history of abdominal pain, weight loss and rectal bleeding. Diagnostic colonoscopy revealed multiple aphthous ulcers within the ileo-caecal region and distal transverse colon, separated by normal mucosa, mimicking skip lesions of Crohn's colitis. Computer topography (CT) scan of the abdomen showed multiple circumferential thickenings involving predominantly the right colon. A clinical diagnosis of colonic Crohn's disease with possible perforation was made. An extended right hemicolectomy was performed due to uncontrolled rectal bleeding. Histopath...

This study aims to determine the association between coronary artery PMCT CS with histologically observed calcification and degree of stenosis of coronary arteries in post-mortem cases. MATERIALS &METHODS: This was a cross-sectional study involving 101 subjects recruited from the National Institute of Forensic Medicine (IPFN) Hospital Kuala Lumpur (HKL) over a period of 15 months, from December 2012 until April 2014. PMCT CS of the coronary arteries was calculated using Agatston-Janowitz score. Histological presence of calcification was observed and the degree of stenosis was calculated using an image analysis tech...

ConclusionRetrosternal goiter causes airway compromise in most patients. Surgery for such cases is a challenging procedure with higher rate of complications, CT-scan is the most single valuable tool in selecting patients for sternotomy before surgery but the final decision for sternotomy is best done during surgery. A team work between a thyroid surgeon and a thoracic surgeon will have better results.

ConclusionWe report a rare case of patient with synchronous liver metastases from gastric cancer who experienced stable disease for 7 years and 3 months following multidisciplinary modalities. Future trials are required to prospectively investigate the established regimen of multidisciplinary treatment.

A 73-year-old woman with a history of a 6-cm juxtarenal abdominal aortic aneurysm who underwent a fenestrated endovascular aortic repair using the Zenith fenestrated endovascular (ZFEN) device (Cook Medical, Bloomington, Ind) presented with a type IA endoleak found on routine surveillance computed tomography angiography (CTA). The previously placed ZFEN device included a scallop for the superior mesenteric artery (SMA) and bilateral stented fenestrations to the renal arteries.

Publication date: Available online 20 August 2019Source: Journal of Forensic Radiology and ImagingAuthor(s): Angi M. Christensen, Gary M. HatchAbstractFractography is the study of fracture surface morphology and its relationship to crack propagation. Recent work has demonstrated the utility of fractography for interpreting crack propagation and impact direction in fractured bones as part of forensic anthropological trauma analyses on skeletonized remains. In this proof-of-concept work, we assess whether the science of fractography can be applied using CT scans of bone fractures. For CT scans to have practical potential for...

In this study, we reviewed the recent literature about the use of WBCT in AAFD, starting from a critical analysis about the biases related to conventional radiography and to non-standing CT. Then, we focused on the effects of load on the 3D architecture of the foot and ankle in AAFD. Finally, we discussed the benefits and future perspectives for the use of WBCT in the management of this condition and as a surgical planning tool as well. Level of Evidence: Diagnostic Level V, expert opinion. See Instructions for Authors for a complete description of levels of evidence.

We present a case of a 60-year-old male patient presented with bilateral inguinal swelling associated with urinary hesitancy and intermittency. He had undergone transabdominal preperitoneal (TAPP) repair for a left inguinal hernia 8 years ago. CT scan confirmed the presence of a bilateral hernia with the bladder herniating bilaterally. He underwent an elective bilateral open Lichtenstein tension-free mesh repair.
