Veterinary Radiology

Scintigraphy is a branch of nuclear medicine. It is an imaging technique in which radionuclides (radioactive elements emitting gamma rays) are administered to a subject.

The CT Scan and MRI Scan for animals should be considered as a sophisticated study, for special problems. Contrast media may be used during CT scanning to enhance the difference in density of various structures.

Radiotherapy Indicated for localized, solid neoplasm that can’t be excised completely and when surgery is expected to do or already failed.

Immediate complications of Radiotherapy observed with in minutes or days after irradiation. For example, Epilation (loss of hair), desquamation of skin, skin erythema, chromosome aberration, haematological depression etc.

Mechanism of action of radiation therapy is by Direct or Target theory and Indirect theory. In which, DNA molecule is the most important target of radiation in the cells.

Radiation therapy in veterinary practices is the use of X-rays or radioisotopes for the treatment of Neoplasms of domestic animals. First radiation therapy in veterinary practices reported by Dr. R.Eberlin of Berlin Veterinary School (1906-1912)

Once the echoes are converted into electrical signals, these are processed and transformed into a visual display of measure of the amplitude of the echo. This is called echo quantification

Ultrasonography has the advantage of being safe, non-invasive procedure that can be performed quickly and easily with proper knowledge of the equipment.

Correct exposure factor, correct positioning should be adopted. Avoid repetition of the process. Unnecessary exposure should be avoided to reduce the x-ray exposure.

The cellular injury causes pathological and physiological changes leading to “radiation sickness” and other manifestation of radiation damage to the body.
