This chapter summarizes the effects of flow in PC-MRI and introduces methods used to analyze and quantify flow. The chapter begins with a brief introduction to low flip angle GRE sequence and need for velocity encoding. Explanation of phase contrast techniques is provided based on the concept of...
Principle of Working of an Electric Bell The working of an electric bell is based on the principle of electromagnetism or the magnetic effect of the current. According to the phenomena of electromagnetism, magnetic fields are associated with moving electric charges. Whenever an electric current flows...
of verbal semantic representations2,3. A functional MRI study suggests that two hemisphere hippocampi perform a complementary principle on navigation with places information processing on the right and temporal sequences on the left4. In a study of neurosurgical patients, hippocampus is shown to have...

This is so because, in the former case, binding of the ligand to receptors competes with binding of endogenous DA to the same receptors to a greater extent than in the control condition. Thus, reduced binding is assumed to reflect an increased release of DA. This displacement principle was ...
Although the organizational principle of the PFC remains unclear, it may be more based on content-oriented associations than on process types (Fuster, 2009, Miller and Cohen, 2001). However, the “content” of PFC representations seems to be more complex/abstract compared with representations in ...
There are numerous types of neural networks in existence, and each of them is pretty useful for image recognition. However, convolution neural networks(CNN) demonstrate the best output with deep learning image recognition using the unique work principle. Several variants of CNN architecture exist; th...
The enterprise obtained the license of OHSAS 180001 "Occupational Health and Safety Management System in 2004 and ISO 14001 "Environmental Management System" in 2005 and always acted with the principle of continuous improvement in the field of environment, occupational health and safety and security. ...
According to the ALARA principle, a very different value and indication list results for paediatric uro-CT. Children are not small adults! As a rule, one should try to avoid CT in children whenever possible. Particularly if high-end US used by experienced operators and MRU is optimally ...
Echocardiography in patients with atrial fibrillation is challenging due to the varying heart rate. Thus, the topic of this expert proposal focuses on an o
