We report an unusual case of a young male with cerebellar hemangioblastoma treated previously for medullary carcinoma of thyroid, whose PET/CT scans revealed a constellation of findings that suggested the rare Von Hippel Lindau syndrome. The diagnosis was clinched by confirming the findings on whole body contrast enhanced computed tomography (CECT) and contrast enha...

We measured ventilation (V) in seven anesthetized, mechanically ventilated, supine Wistar rats. Images of the whole lung were continuously acquired using a dynamic, flat-panel volumetric micro-computed tomography (micro-CT) scanner during ventilation with a xenon/oxygen (Xe-O(2)) gas mixture. Forty time-resolved volumes consisting of eighty 0.45-mm-thick slices (covering the entire lung) were a...

OBJECTIVE The aim of this study was to investigate physiological changes in cardiac area and diameters between inspiratory and expiratory chest computed tomography (CT), and to assess their correlation with lung size change and influence on cardiothoracic ratio (CTR) measurements. MATERIALS AND METHODS The institutional review board of our institution approved this study, and informed consent...

OBJECTIVES Routine application of positron emission tomography/computed tomography (PET/CT) for pancreatic cancer staging remains a controversial approach. The purpose of this study was to reassess the clinical impact of PET/CT for the detection of distant metastasis of pancreatic cancer. METHODS From January 2006 to June 2009, 125 patients with histologically proven pancreatic cancer that ha...

Objectives- to provide a reference anatomy of the bronchial tree of the Jebeer Gazelle by using computed tomographic modality. Design- Experimental study. Animals- Three female Jebeer Gazelle Procedures- Spiral CT images were taken from the thoracic region perpendicular to long axis of the body. CT windows were adjusted as necessary to have optimized images of pulmonary organ. The images ...

Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...

Prostate gland can be structurally evaluated by computed tomography (CT) with taking advantages of tomographic feature and post-contrast parenchymal changes. The current examination initiated to determine association between computed tomographic and cytological results in evaluation of canine prostate. Thirty mature male dogs were included and under gone by both CT and fine needle sampling of p...

Coronavirus disease 2019 (COVID-19) has spread rapidly around the world and many studies have shown these typical rare atypical findings, such as transient pneumothorax, spontaneous pneumomediastinum (SP), well emphysema subcutaneous during hospitalization. This is case in a 56-year-old woman with COVID-19, who presented hospitalization, of low abundance. As her clinic worsened dyspnea impaired...

OBJECTIVE The objective was to quantify the potential economic value of single-photon emission computed tomography (SPECT) with computed tomography (CT; SPECT/CT) versus CT pulmonary angiography (CTPA), ventilation-perfusion (V/Q) planar scintigraphy, and V/Q SPECT imaging modalities for diagnosing suspected pulmonary embolism (PE) patients in an emergency setting. METHODS An Excel-based simu...

OBJECTIVE The purpose of this study was to evaluate the lung computed tomography (CT) findings in fat embolism (FE) syndrome. METHODS We retrospectively evaluated 19 CT examinations of 18 patients with FE syndrome, diagnosed clinically using the Gurd and Wilson criteria. RESULT Fat embolism syndrome showed 3 patterns: negative examination, bilateral interstitial-alveolar involvement, and ad...
