We present a case of cystic falx meningioma. Cystic meningioma is rare and not easy to diagnose preoperatively; it is often misdiagnosed as other tumors, including glial or metastatic tumors with cystic or necrotic changes. This study showed the potential impact of 320-row computed tomography (CT) on image-based diagnostic evaluation of cystic meningioma with special attention to the novel tech...

BACKGROUND Coronary artery anomalies are not common, but could be very serious. OBJECTIVES This study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (MDCT). PATIENTS AND METHODS The results of cardiac MDCT study in 2697 consecutive patients were analyzed retrospectively. Acquisition was performed by a 64-detector row CT machine. ...

A 59-year-old man developed right hemiplegia and total aphasia. His National Institute of Health Stroke Scale score was 27. Serial multi-detector row non-contrast computed tomography (CT) with multiple planar reconstruction (MPR) revealed a hyperdense middle cerebral artery (MCA) sign in the left MCA (Picture A and B, arrow), and a diagnosis of acute ischemic stroke was made. Alteplase (0.6 mg/...

Dear Sir, It is widely recognized that 3-dimensional computed tomography (3D-CT) is useful for diagnosing facial bone fractures.1 However, it can be sometimes difficult to obtain such specialized 3D-CT images from radiologists because of the unusual and specific nature of the request. Moreover, it sometimes takes a long time before the 3D photographs are received. Consequently, we have develope...

PURPOSE This study aimed to assess the results of computed tomography (CT) fluoroscopy-guided vertebroplasty in patients with multiple myeloma, focusing on the frequency and clinical impact of polymethylmethacrylate (PMMA) leaks. MATERIALS AND METHODS From December 2001 to August 2008, 39 patients (17 females, 22 males; mean age, 65±7 years) with multiple myeloma suffering from painful spinal...

Recently, stress myocardial computed tomographic perfusion (CTP) was shown to detect myocardial ischemia. Our main objective was to evaluate the feasibility of dipyridamole stress CTP and compare it to single-photon emission computed tomography (SPECT) to detect significant coronary stenosis using invasive conventional coronary angiography (CCA; stenosis >70%) as the reference method. Thirty-si...

In the 1980s CT imaging of coronary arteries began after the introduction of electron beam CT (EBCT), with the main application being quantification of calcifications in the coronary arteries for risk stratification. In the late 1990s helical multidetector row CT (MDCT), starting with the four-detector row, was used for noninvasive evaluation of suspected coronary artery disease. Initially MDCT...
