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.
