Background Quantitative flow ratio (QFR) is a tool for physiological lesion assessment based
on invasive coronary angiography. Aims We aimed to assess the reproducibility of QFR …

Coronary artery disease is the leading cause of mortality worldwide. Diagnosis is
conventionally performed by direct visualization of the arteries by invasive coronary …

Three dimensional (3D) coronary anatomy, reconstructed from coronary angiography (CA),
is now being used as the basis to compute 'virtual'fractional flow reserve (vFFR), and thereby …

Assessment of distal cerebral perfusion after ischaemic stroke is currently only possible
through expensive and time-consuming imaging procedures which require the injection of a …

Third molar development is used for dental age estimation when all the other teeth are fully
mature. In most medicolegal facilities, dental age estimation is an operator-dependent …

Historically, invasive coronary angiography provided what was once considered the gold-
standard assessment of ischaemic heart disease (IHD). The presence of epicardial coronary …

Background Contrast reflux, which is the retrograde movement of contrast against flow
direction, is commonly observed during angiography. Despite a vast body of literature on …

The present study aimed to evaluate the students' progress in evaluating ultrasound (US)
and cadaveric cardiac images and long-time retention of information. First-year medical …

Background Fractional flow reserve is the 'gold-standard'method for the measurement of
coronary artery stenosis physiological significance. FFR-guided revascularisation has a …

Assessment of lesion-specific ischemia using fractional flow reserve (FFR) profiles derived
from coronary computed tomography angiography (FFRCT) and invasive pressure …
