1. APA Advanced Training Institute 2003: Functional Magnetic Resonance Imaging
APAs Advanced Training Institute in Functional Magnetic Resonance Imaging (fMRI) is an intensive introduction to the field. This 5-day course will provide training and hands-on experience in experimental design and data analysis.

Magnetic Resonance Imaging Magnetic Resonance Imaging is based on using a powerful magnetic field in conjunction with radio-frequency signals and a computer to create images of structures in the body. Magnetic Resonance is most commonly used in evaluation of patients suspected of tumors, multiple sclerosis, inflammatory diseases, disc disease, and cartilage, soft tissue or tendon abnormalities. Current software advances allow noninvasive imaging of the vascular structures. This is referred to as Magnetic Resonance Angiography (MRA). Technologic enhancements are also now available which allow for 2 Dimensional and 3 Dimensional imaging. Specifically, 3 Dimensional imaging of the knee for anterior cruciate ligament injury has shown to be very useful. Some exams do require the injection of a contrast media, usually Gadolinium. This should be avoided in patients with diminished renal function or in women who are breast feeding. Examination Time: 40 minutes to 1 hour

3. Magnetic Resonance Imaging (MRI) Advanced Radiology Consultants
MAGNETIC RESONANCE IMAGING (MRI) Magnetic Resonance Imaging utilizes a magnet to produce high-quality diagnostic images. It is harmless to the patient because no radiation is used. The scanner area is small in the HIGH FIELD strength due to special devices used to enhance the images. Many patients could experience claustrophobia and might need to be pre-medicated. Our OPEN MRI accommodates claustrophobic patients. If there is any possibility of the patient being pregnant or a nursing mother, please notify the scheduler at the office at the time of scheduling. Learn about the various imaging studies and what you need to do to prepare

4. MRI Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) makes pictures of the inside of the body much like regular x-rays but uses a strong magnetic field. The MRI scanner sends the signals to a computer, which manages the information and creates a 3-D image of the tissue being scanned. It then prints it on photographic film or videotape. MRI scans can see through bone and provide clear, detailed pictures of tissues and muscles. You may be asked to lie on a narrow table that can slide inside a large tunnel-like tube inside the scanner. The scanner makes a magnetic field around you. An MRI does not hurt. The table might be cold but a technologist will give you a blanket and pillow to make you comfortable. Sometimes the machine might make loud noises or humming and vibrate. This is a normal part of an MRI. A radiologist, who specializes in MRIs will look at the film or computer and find out what the problem is. Lots of athletes have MRIs for injuries to their muscles and tendons.

5. Principles of Magnetic Resonance Imaging - By Mike Puddephat
Nuclear magnetic resonance (NMR) is a non-invasive means of obtaining clinical images and of studying tissue metabolism in vivo. Bloch and Purcell independently discovered NMR in 1946 (Bloch (1946), Bloch et al. (1946) and Purcell et al. (1946)). Six years later they were awarded the Nobel Prize for their achievements. Since then, the development of NMR spectrometers and NMR scanners has led to the opening up of whole new branches of physics, chemistry, biology and medicine. Jadetzky and Wertz (1956) and Odeblad et al. (1956) employed NMR in chemical analysis for the investigation of molecular structure and molecular motion in solids and liquids. Moon and Richards (1973) and Hoult et al. (1974) were able to obtain biochemical information from cells and tissues. The process of detecting metabolites by NMR is known as magnetic resonance spectroscopy (MRS) and the first MR spectrum of a human tumour was obtained by Griffiths et al. (1981) from a rhabdomyosarcoma on the dorsum of the hand. The process of acquiring two and 3D images by NMR, known as magnetic resonance imaging (MRI), was first illustrated by Lauterbur (1973) who produced a 2D MR image of a phantom. Over the last 20 years, Fourier transform imaging techniques have tremendously accelerated the development of MRI (Kumar et al., 1978).
