Techniques Used in Radiology


Radiology represents a branch of medicine that deals with radiant energy in the diagnosis and treatment of diseases. This field is divided into two broad areas – diagnostic radiology and interventional radiology. A physician who specializes in radiology is known as a radiologist. The outcome of an imaging study does not rely merely on the indication or the quality of its technical execution. Diagnostic radiology specialist represents the last link in the diagnostic chain, as they search for relevant image information to evaluate and finally support a sound diagnosis. Using the diagnostic images, the radiologist or other physicians can often
  • Diagnose the cause of your symptoms
  • Monitor how well your body is responding to a treatment you are receiving for your disease or condition
  • Screen for different illnesses, such as breast cancer, colon cancer, or heart disease
The most common types of diagnostic radiology exams include:
  • Computed tomography (CT), also known as a CAT scan (computerized axial tomography), including CT angiography
  • Fluoroscopy, including upper GI and barium enema
  • Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
  • Mammography
  • Nuclear medicine, which includes such tests as a bone scan, thyroid scan, and thallium cardiac stress test
  • Plain x-rays, which includes chest x-ray
  • Positron emission tomography also called PET imaging or a PET scan
  • Ultrasound


Interventional radiologists use imaging such as CT, ultrasound, MRI, and fluoroscopy to help guide procedures. The imaging is helpful to the doctor when inserting catheters, wires, and other small instruments and tools into the body. This typically allows for smaller incisions (cuts). Doctors can use this technology to diagnose or treat conditions in almost any part of the body instead of needing to directly look inside of your body through a scope (camera) or with open surgery. Interventional radiologists often are involved in treating cancers or tumors, blockages in the arteries and veins, fibroids in the uterus, back pain, liver problems, and kidney problems. The doctor will make no incision or only a very small one. You rarely need to stay in the hospital after the procedure. Most persons need only conscious sedation to relax their body. Examples of interventional radiology procedures include:
  • Angiography or angioplasty and stent placement
  • Embolization to control bleeding
  • Tumor embolization using chemoembolization or Y-90 radioembolization
  • Vertebroplasty and kyphoplasty
  • Needle biopsies of different organs, such as the lungs and thyroid gland
  • Tumor ablation with radiofrequency ablation, cryoablation, or microwave ablation
  • Breast biopsy, guided either by stereotactic or ultrasound techniques
  • Uterine artery embolization
  • Feeding tube placement
  • Venous access catheter placement, such as Ports and PICCs

Radiology/ Radiologist Role In Treatment

Radiologist Plays a Key Role in Healthcare by -
  • Acting as an expert consultant to your referring physician by aiding him or her in choosing the proper examination, interpreting the resulting medical images, and using test results to direct your care.
  • Treating diseases by means of radiation (radiation oncology) or minimally invasive, image-guided therapeutic intervention (interventional radiology)
  • Correlating medical image findings with other examinations and tests
  • Recommending further appropriate examinations or treatments when necessary and conferring with referring physicians.
  • Directing radiologic technologists (personnel who operate the equipment) in the proper performance of quality exams
