PURPOSE To evaluate a diagnostic strategy for pulmonary embolism that combined clinical assessment, plasma D-dimer measurement, lower limb venous ultrasonography, and helical computed tomography (CT). METHODS A cohort of 965 consecutive patients presenting to the emergency departments of three general and teaching hospitals with clinically suspected pulmonary embolism underwent sequential non...

We reported this case to remind neurologists that pulmonary right-to-left shunt is one of the causes paradoxical embolism. A 47-year-old woman was diagnosed with infarction cerebellum vermis by MRI. Atheromatous, immunological, infectious, and hypercoagulable abnormality negated. doubtful arteriovenous malformation (PAVM) accidentally found in process CT angiography subclavian arteries. Then, c...

A 67-year-old woman presented with lower body edema and was found to have a suprarenal inferior vena cava (IVC) obstruction without hepatic vein obstruction and partial anomalous pulmonary venous return (PAPVR) draining the right pulmonary veins to the IVC below the obstructed IVC on CT angiography. The patient underwent retrohepatic cavoatrial bypass with a polytetrafluoroethylene (PTFE) 16-mm...

A 55-year-old woman became increasingly breathless over a 9month period. Systolic pulmonary artery pressure was estimated at 50 mm Hg by echocardiography. CT pulmonary angiography was performed using a dual energy technique whereby datasets are simultaneously acquired at 80 kV and 140 kV. Differential absorption of these energy spectra by iodine molecules in intravenous contrast medium is explo...

• Vol 9 • April 2007 CA Fistulas Detected by MSCT A 57 old man was admitted for exertional dyspnea and chest pain. During workup, a chest computed tomography scan was performed and a very large and unusual arterial structure was observed in the left anterior descending position. The patient was referred for evaluation by cardiac multi-slice CT. Non-invasive coronary angiography was performed us...

Introduction: Describe the profile of patients referred for computed tomography (CT) likely to be scanned with scintigraphy imaging in Togo. Methods: Prospective study carried out from May 15 to August 15 2020 including patients referred for non-traumatic CT scans (excluding strokes) in all the radiology centres in Togo with operational ...

Pulmonary embolism (PE) is a potentially life threatening condition requiring adequate diagnosis and treatment. Computed tomography pulmonary angiography (CTPA) is excellent for including and excluding PE, therefore CT is the first-choice diagnostic imaging technique in patients suspected of having acute PE. Due to its wide availability and low invasiveness, CTPA tends to be overused. Correct i...

Pulmonary arteriovenous malformations (PAVM) are abnormal communications between pulmonary arteries and pulmonary veins, and most commonly congenital in nature. Although rare, it is an important consideration in cyanotic patients of unknown cause. We report 3 cases with diffuse PAVM in children with different clinical manifestations and initial diagnosis was made by transthoracic contrast echoc...
