Good quality MR angiograms of the neck vessels were obtained with the fast 3D sequence in 20 of the 21 patients. One claustrophobic patient was unable to co-operate. The degree of internal carotid artery (ICA) stenosis was graded correctly (compared to DSA) in 21 of 24 cases (87.5 %)....
Radiopharmaceuticals are a group of pharmaceutical drugs that have radioactivity and can be used as diagnostics and therapeutic agents. Contrast media is the substance used to enhance the contrast of an image, hence, making an image more detailed and apparent. Contrast media is increasingly being...
13.Effect of iodine concentration of contrast media on contrast enhancement in the pancreatic CT angiography examination胰腺CT血管造影检查中造影剂浓度对增强效果的影响 14.roentgenographic examination of blood vessels after injection of a radiopaque contrast medium; produces an angiogram.注射造影剂后用放射...
[25]. Furthermore, in our center, patients with very high coronary artery calcium scores (as assessed by the clinical team on the day of the scan) were referred directly for an invasive X-ray coronary angiogram, without performing a contrast enhanced coronary CTA, in order to avoid ...
The intervention was completed by a coronary angiogram to determine final TIMI grade flow. SPECT Prior to opening of the occluded vessel the patients received a body weight-adjusted (350-700 MBq) iv injection of 99 mTc tetrofosmin (Amersham Health, Buckinghamshire, UK) or sestamibi (MIBI, ...
The cycle-consistent GAN (cycle-GAN)35 has emerged as a revolutionary training strategy for generating photo-realistic and high-resolution synthetic images using unpaired data36,37,38. Chandrashekar et al. deployed a two-dimensional (2D) cycle-GAN to synthesize contrast CT angiograms (CTAs) to...
Contrast-enhanced CMR angiography (CE-CMRA) is being increasingly used for diagnosing aortic arch anomalies, planning interventions and follow-up assessment. We sought to establish normal values for the diameters of the thoracic aorta and reference curves related to body growth in children using CE-...
(Right panel and correspondingMovieFile 8) Coronary angiogram (left anterior oblique view) in same patient. Image shows high-grade mid-LAD artery stenosis (white arrow). View video clips online. Several recent publications have addressed the critical clinical question of whether LVO actually ...
FIG. 10B illustrates a digital subtraction angiogram of the aneurysmal aorta and aneurysmal common iliac arteries as well as severe stenoses of the right external iliac (curved arrow) and inferior mesenteric (straight arrow) arteries and a mild stenosis of the left common iliac artery of FIG. ...
For assessing overall blood vessel structure and health it is more useful to project the 3D array of NMR data into a single 2D projection image to produce an angiogram-like picture of the vascular system. The most commonly used technique for doing this is to project a ray from each pixel ...
