Dr. Muhammad Ayub discusses the technical considerations and applications of cardiac CT. He outlines the spatial and temporal resolution, contrast requirements, and radiation exposure of cardiac CT. He then discusses the advantages of cardiac CT including being noninvasive and providing 3D anatomical information. Potential limitations include contrast requirements, radiation exposure, and limited resolution. Applications covered include calcium scoring, CT angiography, assessment of coronary anomalies, cardiac masses, valves, grafts, aorta, pulmonary vessels, and congenital heart disease. Appropriateness criteria for various clinical indications are also provided.
A detailed description of ct coronary angiography and calcium scoring with various aspects regarding the preparation, procedure, limitations and a short review regarding post CABG imaging.

Presentation given at Arab Health congress on Jan. 29th 2013, with information about (dual source) Cardiac CT of the coronary arteries with technical & practical information and some clinical use cases
This is a chapter from Grainger and Allison. I have Coolected all images from chapter 19 with caption in this presentation.
In my opinion it will be very benificial to have this in your android. ,
CAD – leading cause of death
Cardiac SPECT – steady growth in last two decades & played an important role in clinical mangement
Radionuclide ventriculography (MUGA)
First pass studies
PET/CT
Physicians have used palpation to detect differences in tissue stiffness as an aid to diagnosis based on the fact that the mechanical properties of tissues are often dramatically affected by the presence of disease processes such as cancer, inflammation, and fibrosis. Elastography depends on the same differences in mechanical properties between healthy and abnormal tissues using imaging to detect these differences at depths not reachable by manual palpation and presents data in color-coded display, can be performed with ultrasound, using manual pressure or low frequency sonic waves, or by MR Elastography imaging.
Doppler ultrasound of visceral arteriesSamir Haffar
Doppler ultrasound of different diseases of visceral arteries including arterial stenosis and occlusion, arterial aneurysm, artrial pseudoaneurysm, arterio-venous fistula, artrial dissection, and abdominal vascular compression syndromes
