RADIOLOGY
Radiology is the medical branch that dealing with radiation to diagnose and treating disease.
Radiologist – radiologist is the doctor who are specialized to diagnose and treating disease with the help of radio- imaging technology.
Radiographer – radiographer are healthcare professionals who perform the procedure of medical imaging with the help of radio-imaging technology
Radio – imaging = making images of the internal body with the help of radiation.
Type of imaging machines
- X ray
- Ct scan
- Mammography
- Ultrasound
- Mri
- Dexa
- NUCLEAR MEDICINE
Brief introduction–
X ray –
in this we use x rays for imaging, x rays are highly penetrating and ionizing radiation.
Use psp, xray film and digital receptor to record image and scanner to read it.
Fluoroscopy
it is a real time image with the help of x ray. Procedure of this is also same as the x ray.
DARK ROOM – heart of the x ray
It is the area where x ray film is processed with the help of chemical.
Ct – scan
known as computed tomography or computed axial tomography. It uses rotating x ray machine and take different x ray image on different angle to produce virtual slice of body.
Mammography – is also called mammogram. This procedure is for Breast imaging with the help of low ionizing radiation to diagnose the breast cancer, tumor or lump.
Ultrasound –
also known as sonography which is used the high frequency sound waves to diagnose the disease. Basically it is non ionizing radiation which is used to less harmful than x ray and it is also used to diagnose complication of unborn babies.
US DOPPLER – it is used to estimate the blood flow in vessels.
MRI –
also known as magnetic resonance imaging. which uses strong magnetic field to generate images of the internal body.
DEXA-
dual energy x ray absorptiometry, it is use to measure the bone density with the help of x ray imaging.
NUCLEAR MEDICINE –
SPECT – single positron emission computed tomography is used the gamma camera
PET – Positron emission tomography. It uses radioactive material, which act as tracer and PET machined scanned it and shows the activity within the body at cellular level.
