BACKGROUND: The Society of Vascular Surgery (SVS) guidelines currently suggest thoracic endovascular aortic repair (TEVAR) for grade II-IV and non-operative management (NOM) for grade I blunt traumatic aortic injury (BTAI). However, there is increasing evidence that grade II may also be observed safely. The purpose of this study was to compare the outcome of TEVAR and NOM for grade I-IV BTAI and determine if grade II can be safely observed with NOM. METHODS: The records of patients with BTAI from 2004 to 2015 at a Level I trauma center were retrospectively reviewed...

A 43-year old man presented with recurrent pneumonias, episodes of hemoptysis and an enlarging right lower lobe mass. A clear diagnosis was not previously established in spite of multiple radiological evaluations and biopsies. Meticulous review of his CT imaging showed that he had subcarinal calcification on his prior CT scans, which had decreased in size and now multiple new small areas of calcifications were seen in the right lower lobe lesion. An esophago-pulmonary fistula due to migration of mediastinal calcifications was suspected which was identified on careful review of the CT chest and confirmed by esophagogastroduodenoscopy...

Since sorafenib was introduced in 2007 for treating advanced hepatocellular carcinoma (HCC), 15 patients have achieved a complete response (CR) in advanced HCC. However, only four of these reports can be regarded as real CRs involving adequate assessments including imaging, serum tumor markers, and histologic examinations of completely resected specimens. A 54-year-old man with hepatitis C virus (HCV)-related liver cirrhosis (LC) presented to our unit. A CT scan demonstrated a 3.8-cm arterial hypervascular/portal-washout mass in the right lobe and invasion in the right portal vein...

OBJECTIVES: To investigate the diagnostic accuracy of CT coronary artery calcium scoring (CACS) with tin pre-filtration (Sn100kVp) using iterative beam-hardening correction (IBHC) calcium material reconstruction compared to the standard 120kVp acquisition. BACKGROUND: Third generation dual-source CT (DSCT) CACS with Sn100kVp acquisition allows significant dose reduction. However, the Sn100kVp spectrum is harder with lower contrast compared to 120kVp, resulting in lower calcium score values...

PURPOSE: The effect of scaphoid nonunion deformity on wrist function is uncertain due to the lack of reliable imaging tools. Advanced three-dimensional (3-D) computed tomography (CT)-based imaging techniques may improve deformity assessment by using a mirrored image of the contralateral intact wrist as anatomic reference. The implementation of such techniques depends on the extent to which conventional CT is currently used in standard practice. The purpose of this systematic review of medical literature was to analyze the trend in CT scanning scaphoid nonunions, either unilaterally or bilaterally...

Choline is a new PET tracer, which uptake may occur via a choline-specific transporter protein and be accelerated during the proliferation of tumor cells. We report a 61-year-old woman with a metastatic pancreatic tumor from renal cell carcinoma, measuring 35×40 mm. PET scans demonstrated accumulation of (11)C-choline in the metastatic pancreatic tumor, but no accumulation of (18)F-FDG. Choline PET/CT may play a useful and complementary imaging modality, especially when FDG-PET/CT does not show expected findings or when the evaluation of tumor viability is needed, in patients with renal cell carcinoma...

Metachronous ovarian metastasis of colorectal adenocarcinoma is mostly identified within 3 years. Here we present a case of a 64-year-old woman with cecal cancer who underwent right oophorectomy for ovarian metastasis. Imaging was performed because of abdominal bloating; it detected a swollen right ovary with ascites. On laparotomy, a right ovarian tumor and cecal cancer were identified. After right oophorectomy, a diagnosis of unilateral ovarian metastasis from colon cancer was made. One month later, right hemicolectomy was performed...

BACKGROUND: After appropriate initial therapy for patients with stage II-III melanoma, there is no consensus regarding surveillance. Thus, follow-up is highly variable among institutions and individual providers. The National Comprehensive Cancer Network recommends routine clinical examination and consideration of imaging for stage IIB-IIIC every 3-12 mo with no distinction between stages. Detection of recurrence is important as novel systemic therapies and surgical resection of recurrence may provide survival benefits...
