Clinical Dosimetry During the Angiographic Examination

Clinical Dosimetry During the Angiographic Examination

Data are given on the radiation exposure occurring in high volume angiographic suites to physicians and technical personnel. Emphasis is directed to coronary artery examinations since multiple recording modalities are utilized in these examinations and consequently personnel exposures are greater than in other angiographic studies. A comparison of dose exposures when these examinations are done...

Clinical Utility of Angiographic CT with a Flat-detector Angiographic System during Endovascular Procedure

OBJECTIVE We evaluated the feasibility of angiographic computed tomography (ACT) for visualizing stent material in patients who underwent intracranial or extracranial stent placement to treat atherosclerotic lesions or stent assisted coil embolization. MATERIALS AND METHODS We performed intrarterial and intravenous ACT on biplane angiography system equipped with flat panel detectors (Axiom Ar...

Coronary angiographic examination with the dynamic spatial reconstructor.

The dynamic spatial reconstructor (DSR), a high temporal resolution, three-dimensional roentgenographic, computed tomography scanner, was used to scan the coronary arteries of five dogs. After one injection of contrast medium into the left main coronary artery or into the aortic root of each dog, all major epicardial coronary arteries and the septal artery could be imaged. After selective remov...

Dosimetry during intramedullary nailing of the tibia

BACKGROUND Intramedullary nailing under fluoroscopic guidance is a common operation. We studied the intraoperative radiation dose received by both the patient and the personnel. PATIENTS AND METHODS 25 intramedullary nailing procedures of the tibia were studied. All patients suffered from tibial fractures and were treated using the Grosse-Kempf intramedullary nail, with free-hand technique fo...
