The cardiothoracic ratio (CTR), expressing the relationship between the size of the heart and
the transverse dimension of the chest measured on a chest PA radiograph, is a commonly …

Cardiomegaly (and left ventricular size in particular) is well recognized to have
cardiovascular prognostic significance. Cardiac assessment should be routinely performed …

Methods A retrospective study involved the review of 1047 radiological images of adults
aged 21 to 80 years, who had plain postero-anterior chest radiographs between January …

Background: Heart size is an important and effective parameter in chest X-ray (CXR)
interpretation. Studies indicate that, especially in middle-aged men, increased …

Purpose To examine the accuracy of the cardiothoracic ratio (CTR) at routine computed
tomography (CT) of the chest to diagnose cardiomegaly by using echocardiography (ECHO) …

Introduction: The study of cardiac size is important for the diagnosis of various types of
cardiac diseases such as left ventricular enlargement due to aortic stenosis and right …

ABSTRACT A chest x-ray is the most commonly used modality for detecting cardiomegaly,
and the cardiothoracic ratio (CTR) has been used as an important tool for estimating the …

To determine whether or not cardiomegaly identified on chest radiograph (CXR) is indicative
of true cardiomegaly as determined using echocardiography (echo) as the gold standard …

The cardiothoracic ratio (CTR) is considered to be a reliable detector of cardiomegaly on
computed tomography for livings, with a threshold of 0.5. Our study aimed to establish an …

This is a cross-sectional study carried out to study the validity of the cardiothoracic ratio as a
predictor of cardiac enlargement. The study involved 150 patients attending Alsader …
