Three-dimensional images by helical CT scan with intra-arterial injection of diluted contrast medium.
Eighty-seven patients with primary or metastatic brain tumors who were admitted to the National Cancer Center Hospital since April 1996, underwent a helical CT scan during cerebral angiography using the IVR-CT system (Toshiba Medical Systems, Tokyo, Japan), which comprised a digital subtraction angiography system (KXO-80C/DFP-2000A) and a helical CT scanner (X-Vision, Toshiba Medical Systems, T...
متن کاملThree-dimensional helical CT angiography of skull base meningiomas.
PURPOSE To describe the findings of skull base meningiomas on three-dimensional CT angiograms obtained with helical scanning and to evaluate the usefulness of this method. METHODS Fifteen patients who had a meningioma near the skull base were examined with helical CT after receiving an intravenous bolus injection of contrast material. RESULTS All meningiomas had either a honeycomb (12 patie...
متن کاملOverlooked blunt bronchial rupture detected by three-dimensional helical-CT.
A 34-year-old man was referred to for persistent dyspnea 6 months after a blunt chest trauma with subcutaneous emphysema and bilateral pneu-mothoraces, however, without initial bronchoscopy. The three-dimensional CT reconstruction revealed a stenosis of the intermedius bronchus, confirmed by bronchoscopy and successfully treated by bronchial sleeve resection (Fig. 1). Fig. 1. The arrow shows th...
متن کاملThree-Dimensional Detection of Pulmonary Nodules in Chest CT Images
Small pulmonary nodules are radiologic findings that represent an important challenge in diagnosis systems. While these nodules are the major indicator for lung cancer and metastasis, their properties like size and location play an important role in classifying the benign one from the malignant. Estimating the growth rate of the nodule size states the degree of malignancy. This paper presents a...
متن کاملDynamic evaluation of pelvic floor reconstructive surgery using radiopaque meshes and three-dimensional helical CT.
PURPOSE This prospective study was performed to achieve visualization of the reestablishment of anatomy after reconstructive surgery in the different pelvic compartments with non-absorbable radiopaque meshes, providing valuable anatomic information for surgeons implanting meshes. MATERIALS AND METHODS A total of 30 female patients with stress urinary incontinence (SUI), anterior and posterior...
