Acr–Nasci–Sir–Spr Practice Parameter for the Performance and Interpretation of Body Computed Tomography Angiography (Cta)
The American College of Radiology, with more than 30,000 members, is the principal organization of radiologists, radiation oncologists, and clinical medical physicists in the United States. The College is a nonprofit professional society whose primary purposes are to advance the science of radiology, improve radiologic services to the patient, study the socioeconomic aspects of the practice of radiology, and encourage continuing education for radiologists, radiation oncologists, medical physicists, and persons practicing in allied professional fields. The American College of Radiology will periodically define new practice parameters and technical standards for radiologic practice to help advance the science of radiology and to improve the quality of service to patients throughout the United States. Existing practice parameters and technical standards will be reviewed for revision or renewal, as appropriate, on their fifth anniversary or sooner, if indicated. Each practice parameter and technical standard, representing a policy statement by the College, has undergone a thorough consensus process in which it has been subjected to extensive review and approval. The practice parameters and technical standards recognize that the safe and effective use of diagnostic and therapeutic radiology requires specific training, skills, and techniques, as described in each document. Reproduction or modification of the published practice parameter and technical standard by those entities not providing these services is not authorized. Revised 2021 (Resolution 47)* ACR–NASCI–SIR–SPR PRACTICE PARAMETER FOR THE PERFORMANCE AND INTERPRETATION OF BODY COMPUTED TOMOGRAPHY ANGIOGRAPHY (CTA) PREAMBLE This document is an educational tool designed to assist practitioners in providing appropriate radiologic care for patients. Practice Parameters and Technical Standards are not inflexible rules or requirements of practice and are not intended, nor should they be used, to establish a legal standard of care1. -

The outer diameter of the integrated probe is 0.69 mm, which is small enough for imaging in human coronary arteries. This probe, which has high resolution and deep tissue penetration, is designed to identify vulnerable atherosclerotic plaques in coronary arteries. The first in vivo images of a rabbit abdominal aorta obtained by the integrated OCT-US probe are presented. Keywords: atherosclerosis, vulnerable plaque, intravascular ultrasound, optical coherent tomography ABSTRACT Coronary artery atherosclerosis is a major public health problem associated with high clinical morbidity and mortality. For over 20 years, intravascular ultrasound (IVUS) imaging has been a standard diagnostic tool for atherosclerosis1. Recently, optical coherence tomography (OCT) with high resolution, has been applied to intravascular imaging because it enables direct imaging of thin fibrous cap2, one of the key feature of vulnerable atherosclerotic plaque, and tissue responses to stent implantation1. -

Equilibrium Radionuclide Angiography/ Multigated Acquisition
EQUILIBRIUM RADIONUCLIDE ANGIOGRAPHY/ MULTIGATED ACQUISITION Equilibrium Radionuclide Angiography/ Multigated Acquisition S van Eeckhoudt, Bravis ziekenhuis, Roosendaal VJR Schelfhout, Rijnstate, Arnhem 1. Introduction Equilibrium radionuclide angiography (ERNA), also known as radionuclide ventriculography (ERNV), gated synchronized angiography (GSA), blood pool scintigraphy or multi gated acquisition (MUGA), is a well-validated technique to accurately determine cardiac function. In oncology its high reproducibility and low inter observer variability allow for surveillance of cardiac function in patients receiving potentially cardiotoxic anti-cancer treatment. In cardiology it is mostly used for diagnosis and prognosis of patients with heart failure and other heart diseases. 2. Methodology This guideline is based on available scientifi c literature on the subject, the previous guideline (Aanbevelingen Nucleaire Geneeskunde 2007), international guidelines from EANM and/or SNMMI if available and applicable to the Dutch situation. 3. Indications Several Class I (conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective) indications exist: • Evaluation of left ventricular function in cardiac disease: - Coronary artery disease - Valvular heart disease - Congenital heart disease - Congestive heart failure • Evaluation of left ventricular function in non-cardiac disease: - Monitoring potential cardiotoxic side effects of (chemo)therapy - Pre-operative risk stratifi cation in high risk surgery • Evaluation of right ventricular function: - Congenital heart disease - Mitral valve insuffi ciency - Heart-lung transplantation 4. Contraindications None 5.

Comparison of Echocardiography and Angiography in Determining the Cause of Severe Aortic Regurgitation
Br Heart J: first published as 10.1136/hrt.51.1.36 on 1 January 1984. Downloaded from Br Heart J 1984; 51: 36-45 Comparison of echocardiography and angiography in determining the cause of severe aortic regurgitation NICHOLAS L DEPACE, PASQUALE F NESTICO, MORRIS N KOTLER, GARY S MINTZ, DEMETRIOS KIMBIRIS, INDER P GOEL, E ELAINE GLAZIER-LASKEY, JOHN ROSS From the LikoffCardiovascular Institute, Hahnemann University, Philadelphia, Pennsylvania, USA SUMMARY To assess the accuracy of echocardiography in determining the cause of aortic regurgita- tion M mode and cross sectional echocardiography were compared with angiography in 43 patients with predominant aortic regurgitation. Each patient had all three investigations performed during the same admission to hospital. In each instance, the cause of aortic regurgitation was confirmed at surgery or necropsy. Seventeen patients had rheumatic aortic valve disease, 13 bacterial endocarditis with a perforated or partially destroyed cusp, five a biscuspid aortic valve (four with a history of endocarditis), and eight aortic regurgitation secondary to aortic root dilatation or aneurysm. Overall sensitivity of echocardiography and aortography was 84% in determining the cause of aortic regurgi- tation. Thus, rheumatic valve disease and endocarditis appear to be the most common causes of severe aortic regurgitation in this hospital based population. Furthermore, echocardiography is a sensitive non-invasive technique for determining the cause of aortic regurgitation and allows differentiation of valvular from root causes of aortic regurgitation. Aortic regurgitation may be caused by valvular dis- ment for predominant aortic regurgitation were http://heart.bmj.com/ ease, aortic root disease, or a combination of both. reviewed. -

Measurement of Peak Rates of Left Ventricular Wall Movement in Man Comparison of Echocardiography with Angiography
British HeartJournal, I975, 37, 677-683. Br Heart J: first published as 10.1136/hrt.37.7.677 on 1 July 1975. Downloaded from Measurement of peak rates of left ventricular wall movement in man Comparison of echocardiography with angiography D. G. Gibson and D. J. Brown From the Cardiac Department, Brompton Hospital, London, and the Medical Computer Centre, Westminster Hospital, London Estimates ofpeak systolic and diastolic rates of left ventricular wall movement were made in 23 patients by echocardiography and angiocardiography. Echocardiographic measurements were calculated as the rate of change of the transverse left ventricular dimension, derived continuously throughout the cardiac cycle. These were compared with similar plots of transverse left ventricular diameter, in the same patients, derived from digitized cineangiograms taken within IO minutes of echocardiograms. The results indicate close correlation between the two methods, and suggest that either can be used to measure peak rates of left ventricular wall movements in patients with heart disease.
