Cardiac MRI consists of using MRI to study heart anatomy and pathology.
Main advantages of cardiac MRI in comparison with other techniques are:
a better definition of soft tissues
use of different types of sequences improves diagnostic accuracy
avoid ionising radiation
Maximum Intensity Projection (MIP) consists of projecting the voxel with the highest attenuation value on every view throughout the volume onto a 2D image 1.
Such an algorithm is rather simple: for each XY coordinate, only the pixel with the highest Hounsfield number along the Z-axis is represe...
Minimum intensity projection (MinIP) is a data visualization method that enables detection of low-density structures in a given volume. The algorithm uses all the data in a volume of interest to generate a single bidimensional image, in other words, its consists of projecting the voxel with the ...
An octreoscan is a scinitigraphic study that uses 111In labelled octreotide which is a somatostatin analog. It is particularly useful for assessment of neuroendocrine tumours.

The standard uptake value (SUV) is a simple way of determining activity in PET imaging, most commonly used in Flourodeoxyglucose (FDG) imaging. It is also known as the dose uptake ratio (DUR). As the name suggests it is a mathematically derived ratio of tissue radioactivity concentration at a p...
Xenon-127 is a radiopharmaceutical principally used when a performing VQ scan. It is an not widely used alternative to xenon-133 with the main advantage being a higher proton energy allowing for post perfusion scanning.
photon energy: 203 KeV
physical half life: 36.3 days
