History and Science Behind MRI: Open or Closed Case? Magnetic Resonance Imaging (MRI) has been called one of the most comprehensive and efficacious diagnostic imaging modalities in medical history. It became a viable clinical technique in 1982 and during its relatively short lifetime has become the primary imaging modality for investigations of the brain‚ spinal cord‚ spine‚ cancellous bone‚ and joints. It is widely used for the identification and staging of tumors‚ investigations of large

INTRODUCTION: Magnetic Resonance Imaging(MRI) is a non invasive medical imaging method widely used in hospitals and in research. In year 1946 Felix Bloch of Standard /university and Edward Purcell of Harvard University made the first succesful nuclear magnetic resonance experiment to study chemical compounds‚ they were awarded the Nobel Prize for physics in 1952. In early 1980 ’s the first human magnetic resonance imaging( MRI) scanners became available‚ producing images of the inside of the

intentions to form and operate a vascular imaging lab that is separate and independent of the present vascular lab. Our intentions are to initiate this process and be fully operational by June 15‚ 2016. Over the last several years‚ the clinic’s vascular imaging lab policy has led to the exclusion of full participation of multiple members of the Heart and Vascular department who are fully trained and qualified to supervise and interpret vascular imaging studies. Excluding a physician from providing

As I address the topic of potential stumbling blocks physical therapists will confront in the pediatric arena in my geographical area in regards to radiologic imaging I would like to divide them in different aspects: philosophical‚ clinical/educational‚ and financial. First‚ physicians‚ physical therapists‚ and administrators need to welcome the concept of PT’s actively participating in the recommendation and understanding of radiologic studies and modalities. If MD’s ‚ managerial staff and even

Magnetic resonance imaging (MRI) is a type of scan that produces detailed images of the inside of the body using radio waves and strong magnetic fields without using radiation. An MRI scanner is a large tube that contains powerful magnets. During the scan‚ you lie inside the tube. Almost any part of the body can be examined using an MRI‚ including the brain and spinal cord‚ bones and joints‚ heart and blood vessels‚ internal organs‚ and breasts. MRI scans are safe and painless. Almost everyone

The decision to perform CT/CBCT imaging depends on both the initial radiographic valuation and the clinical findings. If the plain radiographs are negative‚ with no signs of fracture‚ no fluid levels‚ no mucosal thickening of the sinuses‚ and no orbital or soft tissue emphysema and there is no indication of penetrating injury‚ then the chance of finding a significant midface fracture on CT/CBCT evaluation. There are very high incidence of intracranial damage in such patients‚ and there are important

Child abuse is a very serious issue within the United States‚ its lead to about 1‚400 deaths per year. It’s an ongoing issue that can be decreased by the help of Radiologists. I picked the article “Imaging in child abuse”. In child abuse cases it is detectable to diagnosis child abuse in radiologic examinations. The radiologist is an important part of child abuse because they caring read the exams in finding of child abuse and directly associate their suspicious findings with the child’s ordering
