Stroke is a major cause of morbidity and mortality worldwide, and effective treatment requires rapid diagnosis and recognition of relevant vascular lesions. In this review we will discuss the usefulness and versatility of computed tomography angiography in the setting of stroke, be it ischemic or hemorrhagic, minor or disabling. Furthermore, we also highlight how we use computed tomography angiography in decision making in transient ischemic attacks, acute disabling ischemic stroke, and hemorrhagic stroke.

In a retrospective study of CT examinations of liver tumours in 37 patients intra- and extrahepatic tumour growth was estimated in order to see if resectability could be predicted. The findings were compared with the evaluation at laparatomy. Four out of 15 tumours, resectable according to CT, turned out to be unresectable and 9 out of 37 CT examinations did not reveal the total extent of tumour growth. A more reliable preoperative radiologic assessment may be obtained by improvement of current CT techniques, by computed tomographic angiography, intraoperative ultrasound or MR imaging.

Coronary artery disease affects more than 385000 persons annually and continues to be a leading cause of death in the United States. Recently, the number of available noninvasive cardiac diagnostic tests has increased substantially. Nurses should be knowledgeable about available noninvasive cardiac diagnostic testing. The common noninvasive cardiac diagnostic testing procedures used to diagnose coronary heart disease are transthoracic echocardiography, stress testing (exercise, pharmacological, and nuclear), multidetector computed tomography, coronary artery calcium scoring (with electron beam computed tomography or computed tomographic angiography), and cardiac magnetic resonance imaging. Objectives include (1) describing available methods for noninvasive assessment of coronary artery disease, (2) identifying which populations each test is most appropriate for, (3) discussing advantages and limitations of each method of testing, (4) identifying nursing considerations when caring for patients undergoing various methods of testing, and (5) describing outcome findings of various methods.
