Frequently Asked Questions
CT Scans (Computed Tomography):
A CT scan, or computed tomography, uses X-rays and computer technology to create detailed cross-sectional images of the body. It works by rotating an X-ray source around the patient, capturing multiple images from different angles, which are then reconstructed by a computer to create detailed 3D images.
While CT scans involve radiation exposure, the benefits of obtaining detailed diagnostic information often outweigh the risks. However, it’s essential to discuss the risks and benefits with your healthcare provider, especially if you are pregnant or have concerns about radiation exposure.
X-rays are a form of electromagnetic radiation, and exposure to high doses of ionizing radiation, such as those used in X-rays, can increase the risk of cancer. This risk is primarily associated with repeated or high-dose exposures over time. However, the risk from a typical medical X-ray, which uses a low dose of radiation, is generally very low and outweighed by the benefits of accurate diagnosis and treatment.
Medical professionals take precautions to minimize radiation exposure during X-ray procedures, such as using lead shielding and limiting the number of exposures whenever possible. Additionally, the benefits of the diagnostic information obtained from X-rays often far outweigh the small potential risk of cancer.
The time it takes to receive your CT scan report can vary, but it’s typically within a few days.
Having an X-ray typically doesn’t affect your ability to give birth. However, if you are pregnant or suspect you might be, it’s crucial to inform your healthcare provider before undergoing any imaging procedures, as they may suggest alternative methods to avoid unnecessary radiation exposure to the fetus.
Cardiology Examinations:
An echocardiogram, or echo, is a non-invasive test that uses ultrasound waves to create images of the heart. It helps assess the structure and function of the heart, including the pumping action, valve function, and blood flow. It is commonly used to diagnose and monitor heart conditions such as heart failure, valve disorders, and congenital heart defects.
An ECG measures the electrical activity of the heart and is used to detect abnormalities in heart rhythm, such as arrhythmias, heart attacks, and other cardiac conditions. It provides valuable information about the heart’s health and function.
Ultrasound:
A biopsy involves the collection of tissue samples for diagnostic purposes. During an ultrasound-guided biopsy, a radiologist uses ultrasound imaging to visualize the target tissue or mass and guide the placement of a needle for sample collection, ensuring accuracy and minimizing risks.
Color Doppler ultrasound is a technique that combines traditional ultrasound with Doppler imaging to visualize blood flow within the body’s blood vessels. It helps assess blood flow patterns and detect abnormalities such as clots, narrowing of vessels, or abnormalities in blood flow direction.
Teleradiology:
Teleradiology involves the transmission of radiological images from one location to another for interpretation and consultation. It enables remote access to radiological expertise, facilitates timely diagnosis and treatment decisions, and improves patient care, especially in areas with limited access to radiologists or during off-hours.
General Check-up/Medical Routine Check-up:
X-rays and CT scans both use radiation to create images of the body, but they differ in their technology and the types of images they produce. X-rays provide 2D images of bones and soft tissues, while CT scans offer detailed 3D images of internal organs, bones, and tissues.
A barium study involves swallowing a contrast material (barium) followed by X-ray imaging to visualize the gastrointestinal tract. It helps diagnose conditions such as ulcers, tumors, or strictures in the esophagus, stomach, or intestines.
