Valuable information of Nuclear Medicine &diagnostic &treatment

 

Information  of nuclear medicine ,its diagnostic,and treatment

 

 

By Iftekhar chowdhury .

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  clinical features,a) weight loss,weight gain,constipation,rough skin,

Very impotents for the hormone estimation in nuclear medicine center,

TSH TEST , Renogram,renal trauma,renal failure, bone  scintigraphy,

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

a)      Treatment of hyperthyroidism, with Rai-131,& its long fellow up .

b)      Treatment of thyroid cancer and life long fellow up.

c)      Treatment of bone pain metastases sr -89,sm -153,p-32.

d)     Intra cavity therapy (y-90,au -190)

e)      Indication for thyroid scanning,

f)       A,)palpable thyroid nodule,

g)      Nodule function-normal,hyperfunctiong,

h)      Nodule number –solitary,or multiple,

i)        Nodule size,shape,and position,of tumor.

j)        Enlarged thyrid gland,b,gland function-size,shape,postion,

k)      Presence of nodular component,,presence of residual tissue,

l)        Normal thyroid scan,

m)    Diffusely enlarged thyroid,cold nodular goiter,left lobe,

n)      Hotnodule,right lobe,multi nodular goitre, treatment of thyroid disease .

o)      Hyperthyroidism.

p)      Clinical features,

Tremor,

Sweating,loss of weight,increase appetite,diarrhea,

Insomina,

Diagnosed by hormone estimation,

T-3,T -4,TSH,

 

Thyerapy 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 static bone scan,osteoarthritic changes  ,bone metastasis,0normal brain scan,brain tumor.normal HIDA .scan. read and comments .
