We aimed to determine if the image quality and vascular enhancement are preserved in computed tomography pulmonary angiography (CTPA) studies performed with ultra-low contrast and optimized radiation dose using high-pitch helical mode of a second generation dual source scanner.

Computed tomography (CT) pulmonary angiography (CTPA) examination has been frequently applied in detecting suspected pulmonary embolism (PE). How to reduce radiation dose to patients is also of concer...
Incidence of transient interruption of contrast (TIC) - A retrospective single-centre analysis in CT pulmonary angiography exams acquired during inspiratory breath-hold with the breathing command: "Please inspire gently!"
To assess the occurrence of transient interruption of contrast (TIC) phenomenon in pulmonary computed tomography angiography (CTPA) exams performed in inspiratory breath-hold after patients were told ...
To test ultra-low-dose computed tomography (ULDCT) scanning protocols for the detection of pulmonary nodules (PN).
Currently, there is an increasing interest in noninvasive imaging of cardiovascular system such as computed tomography coronary angiography (CCTA). The risks of radiation-induced cancer and contrast-i...
The incidence of contrast-induced acute kidney injury (CI-AKI) is particularly high in patients with severe chronic kidney disease (CKD). Novel contrast-sparing strategies are warranted to guarantee t...
Phase III diagnostic trial to demonstrate that functional lung MRI can replace VQ-SPECT in a diagnostic strategy for patients with suspected CTEPH where positive findings are verified with...
This is a multi-site, randomized, investigator-initiated pilot study to evaluate the efficacy of investigational techniques to reduce fluoroscopy time or radiation dose and the amount of r...
Pulmonary embolism is a common pathology in the general population, whose suspicion is based on the clinical and dosage of D-dimers in particular. The key examination for the diagnosis of...
Computed tomographic pulmonary angiography (CTPA) is considered the gold standard for the diagnosis of pulmonary embolism (PE). PE is a potentially fatal disease in which a thrombus is lod...
Examine the feasibility and efficacy of individually optimized uniform contrast enhancement in CT pulmonary angiography (CTPA) for the diagnosis of pulmonary thromboembolic disease.
Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
Radiography of blood vessels after injection of a contrast medium.
Radiography of the vascular system of the brain after injection of a contrast medium.
Radiography of the vascular system of the heart muscle after injection of a contrast medium.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.

Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
