Nuclear medicine is a medical specially that involved the
uses of small amounts of radioactive material to help diagnostic and treat a
variety of diseases.
The radio isotopes used in nuclear medicine emit gamma rays
that can be detected externally by special type of camera ;gamma or pet camera
Radio-pharmaceuticals are substances that are attracted by
specific organs,bones ,tissues.
Radioactivity;is the property of a materials in which continuously emits energy ,eg,tc-99m
,1-131 and these materials are called isotopes,
Nulear medicine is very important now a days for the
following application,
Diagnostic purposes, Thyroid scan, Renogram & rental
scan,Bone scan,Myocardial perfusion,imaging, Liver scan,,Brain scan, Hida
scan,BMD,
Its Therpeutic, treatment of hyperthyroidism with Rai-131
& life long fellow up, treatment of thyroid cancer ,life long fellow up,
treatment of hypothyroidism, treatment of bone pain
It is very for
thyroid scanning view nodule
function,normal ,nodule size,shape, position, its enlarged thyroid gland, gland
function, its preence of nodular component
Hypothyroidism

dose ,75-100mcl.
Renography
& renogram
Renography
&is the method of monitoring the arrival up take and elimination of the
radiopharmacutical by the kidneys,s to give an assessment of individual rental
function .renental function is evaluated by a graphical presentation of tme and
activity curve known as a renogram .
And
doing Bone scintigraphy ,
Assessment
of risk of fracture , dose 15-20 mcl.
Normal
