Types of Radiology Scans

In our mission to make second opinions on radiology scans accessible and affordable for all, we have put together this guide to introduce you to the diverse world of radiology scans, shedding light on the various types that play a crucial role in diagnosing and monitoring medical conditions.

Contrast X-rays

X-rays with Contrast use a contrast medium to enhance the visibility of specific tissues or organs. This technique allows our radiologists to capture detailed images, aiding in detecting abnormalities that might be otherwise difficult to identify.

Intravenous Urogram

Intravenous urography involves using contrast dye to highlight the urinary system on X-ray images. This scan helps diagnose conditions affecting the kidneys, bladder, and ureters, such as kidney stones, tumors, or urinary tract infections.

CT Scan

CT scans utilize X-rays and advanced computer technology to create detailed cross-sectional images of the body. This imaging technique is invaluable for detecting a wide range of conditions, from bone fractures and organ abnormalities to tumors and vascular issues.

CT Scan

MRI employs powerful magnets and radio waves to generate detailed images of the body's soft tissues, including the brain, spinal cord, and joints. This non-invasive and radiation-free technique is particularly effective in diagnosing neurological disorders, joint injuries, and soft tissue abnormalities.


Mammography is a specialized X-ray technique focused on breast imaging. This essential screening tool aids in the early detection of breast cancer by capturing detailed images of breast tissue. Regular mammograms are crucial for maintaining breast health and identifying abnormalities in their early stages.

PET Scan

PET scans involve injecting a small amount of radioactive material, allowing the visualization of metabolic processes within the body. This imaging technique is instrumental in cancer diagnosis, staging, and monitoring treatment response by highlighting areas with increased metabolic activity.

Bone Densitometry

Bone densitometry, often performed using dual-energy X-ray absorptiometry (DEXA), measures bone mineral density to assess bone health and the risk of osteoporosis. This scan is crucial in identifying conditions that affect bone strength and integrity.


Fluoroscopy is a dynamic imaging technique that uses a continuous X-ray beam to create real-time moving images of internal structures. It is commonly used for procedures such as barium studies, joint injections, and assessing the function of certain organs.

Nuclear Medicine Scans

Nuclear medicine scans involve using small amounts of radioactive materials (tracers) to diagnose and treat diseases. This includes procedures like bone scans, thyroid scans, and cardiac stress tests, providing valuable insights into organ function and abnormalities.


Ultrasound uses high-frequency sound waves to produce images of internal structures in real-time. This non-invasive and radiation-free imaging modality is widely used for prenatal imaging, assessing abdominal organs, and guiding procedures such as biopsies.

Doppler ultrasound

A Doppler ultrasound is a type of diagnostic imaging that uses high-frequency sound waves to produce images of blood vessels and the flow of blood through them. They are often detect blockages or narrowing in arteries (stenosis) that can lead to decreased blood flow.


A SPECT scan uses radioactive tracers and special cameras to create 3D images of the inside of your body. SPECT stands for single-photon emission computed tomography. It can detect blood flow and activity in your brain, heart and other organs.


A fistulogram, also known as a fistulography, is an imaging test used to examine the internal opening and track of an abnormal passageway in the body known as a fistula. In this minimally invasive procedure, a radiologist injects a contrast dye into the fistula so they can take X-ray images to determine where the abnormal pathway begins and ends, as well as what organs or structures it connects.

Cone Beam CT

Cone-beam computed tomography or CBCT is a type of medical scan that uses x-rays to create 3D images of your teeth, mouth, and jaws. CBCT scans allow for more detailed imaging than traditional dental x-rays and are commonly used to diagnose issues related to your oral health.


Cystography is a radiographic examination that focuses on imaging the urinary bladder. It is commonly used to diagnose issues such as bladder infections, abnormalities, or problems with urinary system function.


Sialography is a specialized X-ray examination of the salivary glands. By injecting a contrast medium, this procedure helps visualize the ductal system of the salivary glands, aiding in diagnosing conditions such as stones or blockages.

We believe in empowering our patients with knowledge about the diagnostic procedures they may undergo. This article serves as a brief overview of some of the key radiology scans. Your health is our priority, and we are here to provide you with exceptional second opinions on radiology scans and procedures.
