Low-dose CT pulmonary angiography on a 15-year-old CT scanner: a feasibility study
BACKGROUND Computed tomography (CT) low-dose (LD) imaging is used to lower radiation exposure, especially in vascular imaging; in current literature, this is mostly on latest generation high-end CT systems. PURPOSE To evaluate the effects of reduced tube current on objective and subjective image quality of a 15-year-old 16-slice CT system for pulmonary angiography (CTPA). MATERIAL AND METHO...
متن کاملUltra Low Dose CT Pulmonary Angiography with Iterative Reconstruction
OBJECTIVE Evaluation of a new iterative reconstruction algorithm (IMR) for detection/rule-out of pulmonary embolism (PE) in ultra-low dose computed tomography pulmonary angiography (CTPA). METHODS Lower dose CT data sets were simulated based on CTPA examinations of 16 patients with pulmonary embolism (PE) with dose levels (DL) of 50%, 25%, 12.5%, 6.3% or 3.1% of the original tube current sett...
متن کاملLow radiation dose imaging of myocardial perfusion and coronary angiography with a hybrid PET/CT scanner
OBJECTIVES To test the image quality and feasibility of a sequential low radiation dose protocol for hybrid cardiac PET/CT angiography (CTA). BACKGROUND Multidetector computed tomography (MDCT) is a non-invasive method for coronary angiography. The negative predictive value of MDCT is high but perfusion imaging has a role in detecting functional significance of coronary lesions. This has enco...
متن کاملSubmillisievert standard-pitch CT pulmonary angiography with ultra-low dose contrast media administration: A comparison to standard CT imaging
OBJECTIVES To evaluate the image quality and radiation dose of submillisievert standard-pitch CT pulmonary angiography (CTPA) with ultra-low dose contrast media administration in comparison to standard CTPA. MATERIALS AND METHODS Hundred patients (56 females, 44 males, mean age 69.6±15.4 years; median BMI: 26.6, IQR: 5.9) with suspected pulmonary embolism were examined with two different prot...
متن کاملRadiation dose from single-heartbeat coronary CT angiography performed with a 320-detector row volume scanner.
PURPOSE To determine radiation doses from coronary computed tomographic (CT) angiography performed by using a 320-detector row volume scanner and evaluate how the effective dose depends on scan mode and the calculation method used. MATERIALS AND METHODS Radiation doses from coronary CT angiography performed by using a volume scanner were determined by using metal-oxide-semiconductor field-eff...
