OBJECTIVES This study intended to determine the effect of varying degrees of lossy Joint Photographic Experts Group (JPEG) compression on detection of coronary angiographic features. Background Compression of digital coronary angiograms facilitates playback of images and decreases cost. There are little data on the effect of compression on the accuracy of coronary angiography. METHODS At six centers, 71 angiographers each reviewed a set of 100 angiographic sequences. The 100 sequences were…

American College of Cardiology/ European Society of Cardiology international study of angiographic data compression phase II. The effects of varying JPEG data compression levels on the quantitative assessment of the degree of stenosis in digital coronary angiography.
TLDR
Compression ratios of 10:1 and 16:1 affected the QCA results negatively and therefore should not be used in clinical research studies.
American College of Cardiology/ European Society of Cardiology international study of angiographic data compression phase III. Measurement Of image quality differences at varying levels of data compression.
American College of Cardiology/European Society of Cardiology International Study of Angiographic Data Compression Phase III: measurement of image quality differences at varying levels of data compression.
TLDR
Compression at CR 6:1 provides equivalence with the original cine runs, and up to which level of Joint Photographic Experts Group JPEG) data compression the perceived image quality and the detection of diagnostic features remain equivalent to the quality and detectability found in uncompressed coronary angiograms.
Evaluation of the Effect of Varying MPEG-2 Compression Ratios on Digital Coronary Angiographic Assessment of Stenosis Severity
TLDR
Kappa statistics between uncompressed image and compressed image at a ratio of 80:1 was significantly lower than that of other compression ratios such as 40:1 and the baseline for further studies on observer performance for motion images is provided.
The international angiographic compression study.
TLDR
The DICOM cardiac standard became universally accepted throughout the world as the only method appropriate for exchange of digital angiographic images in 2000 and has adopted a high-resolution standard, defined as 1024 1024 pixel images with up to 12 bits (4096 levels) of gray scale per pixel.
Lossy JPEG Compression in Quantitative Angiography: the Role of X-ray Quantum Noise
TLDR
By taking into consideration the quantitative effect of quantum noise in QCA, it is shown that the influence of JPEG compression can be neglected for compression factors up to ten at clinically applicable X-ray doses, comparable to that found by visual analysis for aesthetic image quality.
Effect of CT image compression on computer-assisted lung nodule volume measurement.
TLDR
Nodule volumes measured on images compressed to a level of 20:1 differed significantly from those measured on noncompressed images, especially for nodules with ground-glass attenuation, which could affect the assessment of nodule change in size as measured with computer-assisted methods.
An overview of digital compression of medical images: can we use lossy image compression in radiology?

  • 2006
TLDR
Having conducted an extensive literature review, a range of average compression ratios for different modalities and body parts are presented and laid the groundwork for further evaluation with standardized statistical methods to ultimately elaborate acceptable compression guidelines.
Image quality criteria in cardiology.
TLDR
Quality criteria for cardiac cine-angiography were recently agreed as part of a European Research Project, and a scoring system based on these criteria has been developed to allow an 'objective' measurement of the quality of cardiac angiograms.
Telemedicine for cardiac surgery candidates
TLDR
Initial experience using non-sophisticated telemedical transmission of angiograms of cardiac surgery candidates seems to be a promising facility for distantly located centers.

Compression of digital coronary angiograms does not affect visual or quantitative assessment of coronary artery stenosis severity.
Lossy (15:1) JPEG Compression of Digital Coronary Angiograms Does Not Limit Detection of Subtle Morphological Features
TLDR
Fifty image sequences from 31 interventional procedures were viewed both in the original (uncompressed) state and after 15:1 lossyJPEG compression, and experienced angiographers identified dissections, suspected thrombi, and coronary stents.
Digital coronary angiography: advantages and limitations
TLDR
The rapid and accurate quantitation provided by digital angiography will continue to fail to justify more widespread clinical use of the technology until the need for such quantitation can be shown to be not just of prognostic importance but perhaps also of medicolegal importance.
Reproducibility of coronary arteriographic reading in the coronary artery surgery study (CASS).
TLDR
The mean absolute difference between readings of the percent stenosis decreased over the time of the patient enrollment, 1975 to 1978, and may have resulted from major collaborative efforts made during the course of the study to improve the quality of angiography and to standardize the reading of the cine films.
Interobserver Variability in Coronary Angiography
Four experienced coronary angiographers (two radiologists and two cardiologists) independently assessed the location and degree of coronary artery stenosis, and the location and degree of left…
Observer Agreement in Evaluating Coronary Angiograms
TLDR
Analysis of inter- and intraobserver variability showed that angiographic items about which observers were most inconsistent from one reading to the other had the largest interobserver disagreement as well.
Accuracy of individual and panel visual interpretations of coronary arteriograms: implications for clinical decisions.
Variability in the Analysis of Coronary Arteriograms
TLDR
Variability in coronary arteriogram readings was studied by having cine films from ten patients read by eleven readers, and recent experience in reading arteriograms seemed to be the most important characteristic in determining the accuracy of a reader.
Requirements for cardiac interchange media and the role of recordable CD
TLDR
This report is based on an INCIS ’94 presentation by Paul B. Condit, PhD in Mainz, Germany and provides an update on the progress made since then and a discussion of the distinction between archiving and interchange of digital image data.
