The 18F-fluorodeoxyglucosis positron emission tomography associated to computed tomography (18F-FDG PET/CT) accesses the tumor anatomy and metabolic activity, thereby making it possible to characterize a malignant neoplasm in a non-invasive way. The diagnostic approach with 18F-FDG PET/CT spared the heart from a likely futile invasive procedure when detecting a distant metastasis, changed the biopsy site and therapeutic planning.
ConclusionCT was a more effective diagnostic tool for the diagnosis of irreversible gastric necrosis following caustic ingestion than a strategy based on digestive endoscopy and the use of CBSC. CT could eventually replace gastrointestinal endoscopy in the emergency evaluation of gastroesophageal caustic burns.
ConclusionPneumorrachis is usually asymptomatic and is self-limiting. It is a radiological diagnosis and is not a clinical diagnosis. CT scan is considered the preferred diagnostic method for reliable and rapid detection of pneumorrachis. In case of coexistence, The physician should be alert to diagnose and treat the underlying cause for related injuries.In such cases, successful results can be obtained with hyper-oxy therapy (100% oxygen inhalation) and antibiotic prophylaxis without the need for surgical treatment.
ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.
The purpose of this study was to compare the ex vivo bovine liver ablation zone volume data provided by the manufacturer with measured ablation zone volumes on post procedure CT scans following hepatocellular carcinoma ablation with the Solero Microwave Tissue Ablation System (AngioDynamics).
To compare procedure duration and patient radiation dose in PET/CT and CT-guided liver tumor ablation procedures.
This study aimed to determine the effect of implementation of a low-dose computed tomography (CT)-guided thoracic biopsy protocol on (1) radiation doses associated with CT-guided thoracic biopsies and (2) complication rates when compared to standard thoracic biopsy protocol CT.
Electromagnetic tracking (ET) navigation software has been previously shown to reduce radiation dose, number of CT scans, and needle manipulations in biopsy patients. The purpose of our study is to evaluate the safety and efficacy of ET navigation software in patients undergoing microwave ablation of liver tumors.
CT angiography offers excellent anatomic detail necessary for vascular procedural planning including endovascular aneurysm repair (EVAR). However, patients with renal insufficiency are at risk for acute renal failure due to iodinated contrast administration. Catheter-directed CT angiography is a technique in which dilute iodinated contrast is injected into an intra-aortic pigtail catheter during the CT scan. The purpose of this study was to evaluate the safety and efficacy of this technique.
The purpose of our study was to determine the accuracy of a software (EmboGuide Investigational Device, Philips, The Netherlands) in predicting liver perfusion volumes distal to a proximal contrast-enhanced cone-beam computed tomography (CBCT) scan for the purposes of radioembolization planning.
To determine the effect of inferior vena cava (IVC) size on development of complications as determined on post placement CT scan, including filter tilt, penetration, and thrombosis.
