Clinical imaging

In routine clinical imaging the thickness of a sHce is approximately 3 mm and the in-plane resolution approximately 0.8 mm for a 20-cm FOV,...

A set of shim coils usually represents the field expansion according to spherical harmonics. Depending on the required accuracy, more or fewer orders of the expansion are used. Clinical imaging systems usually use only the first order... 

T1, as the thallous ion (Tl+), has been used for imaging heart function under stress and rest conditions since about 1975. The thallous ion distributes in viable heart muscle as a potassium ion mimic, through the Na+-K+ ATPase pump. Clinical images with 201T1 show the infarcted regions of the heart as cold spots or without radioactivity. 2 T1 decays by electron capture with a...

Noninvasive detection of vascular abnormalities is of the utmost importance in clinical imaging. Indeed, a lot of injuries and diseases manifest themselves through modifications of the vasculature [1,2]. For example, abnormal angiogenesis (blood vessel growth) is observed in the development of most tumors. Embolism and atherosclerosis also manifest themselves through alterations of the blood vessels, namely through occlusions. Hemorrhage could also be detected noninvasively, which is crucial in injuries or in diseases such as ulcers [1]. 

High-frequency or diagnostic ultrasound in clinical imaging (3-10 MHz) Medium-frequency or therapeutic ultrasound in physical therapy (0.7-3.0 MHz) Low-frequency or power ultrasound for lithotripsy, cataract emulsification, liposuction, tissue ablation, cancer therapy, dental descaling, and ultrasonic scalpels (18-100 kHz)...

Lesion conspicuity is often better on DWI than on ADC maps, which is the reason why DWI images are preferred by many neuroradiologists for clinical image interpretation. DWI alone may be sufficient in most cases, but differentiation from T2 shine-through effects can be difficult, particularly with... 

In the first part of this chapter we will review the clinical-imaging patterns of acute territorial infarcts and their clinical relevance. 

The " Tc-labelled diars and dmpe chloro compounds [dmpe = bis(l,2-dimethyl-phosphino)ethane] have been synthesized also by Strauss and coworkers , using the method described elsewhere " and applied for evaluating the myocardial kinetics of these agents in normal and ischemic myocardium. The study demonstrated the superiority of dmpe over diars for clinical imaging. The clearance rate from normal and ischemia myocardium has been found to be similar for both diars and dmpe.
