- But which is the best diagnostic method
Magnetic resonance imaging
• This technique is based upon the inherent magnetic properties of certain nuclei • The patient is placed in the strong magnetic field and the protons in the body are excited into a high energy state by application of a radio frequency pulse • When the second field is stopped, the nuclei return to ground state and emit the absorbed energy in the form of a radio signal • This signal is received by a coil that generally surrounds the specimen and converted to an anatomic image through a process of computer- assisted reconstruction MRI is the gold standard for imaging soft tissues and therefore use for examining tumors, trauma of the brain and spinal cords malformations MRI is also helpful in examining the skeleton, including bone, tendons, ligaments, and joints Magnetic Resonance Imaging (MRI or MR) is the most advanced diagnostic imaging tool with non-invasive procedure for complete viewing of the body Fig: Brain tumor in dog and cat Advanced diagnostic methods are • Cost relative • Speed relative • Higher sensitivity • Accurate But which is the best diagnostic method?? • Diagnostic lab should continually evaluate traditional and advanced technology in the light of cost, time, accuracy and sensitivity to get the best diagnostic results References • Maria N.
