Radiology
Doctor Title: Radiologist
Diagnostic and image-guided interventional specialist interpreting X-rays, CT scans, MRIs, and ultrasounds.
What Does a Radiologist Do?
Radiology is the medical specialty that uses medical imaging technology to diagnose and treat diseases seen within the body. Diagnostic radiologists interpret X-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine scans, while interventional radiologists perform minimally invasive image-guided procedures.
Core Clinical Responsibilities:
- Interprets diagnostic medical imaging across all modalities (X-ray, CT, MRI, Ultrasound, PET).
- Produces formal radiologic reports correlating imaging findings with patient clinical histories.
- Performs ultrasound- and CT-guided biopsies of suspicious lung, liver, and abdominal masses.
- Executes minimally invasive interventional vascular procedures (angioplasty, uterine fibroid embolization).
- Oversees patient radiation safety, protocol selection, and contrast agent administration.
When to See a Radiologist
You should consider scheduling an evaluation with a Radiologist if you experience any of the following warning signs or persistent symptoms:
Patients are referred to radiologists by their primary care or specialist physicians for:
Severe trauma, suspected bone fractures, or head injuries requiring emergency CT/X-rays
Persistent headaches, back pain, or neurological deficits requiring high-resolution MRI
Abdominal pain, suspected appendicitis, kidney stones, or gallbladder inflammation requiring ultrasound/CT
Routine screening mammography for early breast cancer detection
Shortness of breath or chronic cough requiring chest radiography
Conditions & Diseases Treated
A Radiologist provides specialized diagnostic workups and therapeutic management for a wide range of conditions, including:
Common Tests & Procedures Ordered
To confirm diagnoses and monitor treatment effectiveness, a Radiologist frequently utilizes the following clinical tests and procedures:
Computed Tomography (CT Scan - Multidetector)
Cross-sectional rotating X-ray tomography generating detailed axial, sagittal, and coronal slices.
Magnetic Resonance Imaging (MRI - 1.5T / 3.0T)
Non-radiation imaging using powerful magnetic fields and radiofrequency pulses for soft tissue resolution.
Ultrasound (Sonography & Color Doppler)
High-frequency sound waves assessing soft-tissue structures, pelvic organs, and blood flow velocities.
Digital Screening Mammography & Tomosynthesis (3D Mammogram)
Low-dose X-ray imaging designed for early breast microcalcification and tissue density evaluation.
Kidney Function Test (Serum Creatinine)

Subspecialties & Advanced Fellowships
Within Radiology, physicians may pursue additional fellowship training to concentrate on specialized surgical procedures or disease subsets:
Frequently Asked Questions
Make the most of your consultation with a Radiologist by coming prepared:
- Inform staff immediately if you have a cardiac pacemaker, metal implants, vascular clips, or severe claustrophobia before an MRI.
- Check fasting instructions if having an abdominal ultrasound or a scan with intravenous contrast.
- Bring all prior imaging CDs and reports from external diagnostic centers for comparison.
