CT Scan in Bhubaneswar

The word "computed tomography," or "CT," describes a computerised X-ray imaging technique in which a patient is exposed to a narrow beam of X-rays that is rapidly rotated around the body. This process produces signals, which the machine's computer processes to create cross-sectional images, or "slices." Compared to traditional X-rays, these slices—known as tomographic images—can provide a doctor with more precise information. A three-dimensional (3D) image of the patient can be created by digitally "stacked" successive slices that the machine's computer has acquired. This makes it easier to identify the patient's basic anatomy as well as potential tumours or anomalies.

At Manipal Hospitals in Bhubaneswar, Odisha, our Radiology Department is equipped with state-of-the-art CT imaging technology, ensuring high-quality diagnostic capabilities for a wide range of medical conditions. Our skilled radiologists and technologists are dedicated to providing exceptional patient care through accurate and efficient imaging services.

FAQ's

CT scans are valuable for identifying diseases or injuries in various parts of the body. For example:

  • Abdominal Tumours or Lesions: CT scans serve as effective screening tools for detecting potential tumours or lesions in the abdomen.

  • Cardiac Conditions: In cases where heart disease or anomalies are suspected, a cardiac CT scan may be requested to assess heart health.

  • Head Imaging: CT scans can capture injuries, tumours, and clots leading to strokes, haemorrhages, and other disorders in the head.

  • Lung Conditions: CT scans can image the lungs to identify conditions such as pneumonia, emphysema, tumours, and pulmonary embolisms (blood clots).

  • Bone Imaging: Due to their ability to provide detailed images, CT scans are particularly useful for imaging complex bone fractures, extensively degraded joints, or bone tumours, surpassing the detail provided by standard X-rays.

Overall, CT scans are versatile diagnostic tools capable of providing detailed images to aid in the detection and diagnosis of a wide range of medical conditions affecting different parts of the body.

A CT scanner utilises a motorized X-ray source that rotates around the circular opening of a doughnut-shaped structure called a gantry, unlike a traditional X-ray, which employs a stationary X-ray tube. During a CT scan, the patient lies on a bed that moves slowly through the gantry while the X-ray tube revolves around them, emitting small beams of radiation through their body. Instead of using film, CT scanners are equipped with specialised digital X-ray detectors positioned directly opposite the X-ray source. These detectors capture the X-rays as they exit the patient and transmit the data to a computer for processing.

The computer may create a 3D representation of the patient that displays the skeleton, organs, and tissues in addition to whatever anomalies the doctor is attempting to find by stacking or displaying image slices separately. Among the many benefits of this approach is its capacity to view slices sequentially or rotate the 3D image in space, which facilitates pinpointing the precise location of potential problems.

  • You should let your healthcare provider know if you are pregnant or suspect you might be.

  • For a CT scan, very little radiation is used. You might wish to inquire with your physician about the dangers associated with the specifics of your case as well as the radiation dosage used during the CT scan.

  • The use of contrast dye increases the risk of an allergic reaction. Patients who are allergic or sensitive to drugs, contrast dye, iodine, or shellfish should tell their doctor. This can lead to weakness, sweating, and difficulty breathing.

  • Inform your doctor beforehand if you have claustrophobia or if you get anxious easily. To help you feel more comfortable, a small sedative may be given to you to take before the surgery.

  • High-resolution CT: This type of CT scan uses extremely thin slices (less than 0.1 inches) to provide detailed images, particularly useful for diagnosing lung diseases and other conditions requiring high-resolution imaging.

  • Spiral or helical CT: Compared to traditional CT scans, the images are obtained faster. More contrast and resolution in the final photos provide more detailed information. Multidetector-row helical CT scanners can be used to learn more about the accumulation of calcium within the heart's coronary arteries. 

  • Ultrafast CT, also known as electron beam CT, is a kind of CT scan that creates images quickly, allowing moving bodily parts, including the heart's chambers and valves, to be seen in a "movie" format. This scan can also be used to learn more about calcium accumulation within the heart's coronary arteries, although helical scanners are far more frequently employed.

  • CT Angiography (CTA): An X-ray image of the blood vessels is called an angiography, sometimes known as an arteriography. Instead of using fluoroscopy or ordinary X-rays, CT angiography employs CT technology to create images of blood vessels, such as the heart's coronary arteries.

  • PET/CT: PET/CT combines positron emission tomography (PET) and CT imaging technologies into a single device. This integrated approach allows for the simultaneous acquisition of metabolic and anatomical information, aiding in the diagnosis and staging of various diseases, including cancer.

  • Enhanced Visualisation: IV contrast, typically containing iodine-based contrast material, enhances the visibility of vascular structures, organs, and other tissues on the CT images. This enhancement improves the clarity and contrast of the images, making it easier for healthcare providers to detect abnormalities or pathology.

  • Improved Diagnostic Accuracy: With the help of IV contrast, healthcare providers can obtain clearer and more detailed images of the body's internal structures. This enhanced visualisation enables them to identify potential irregularities, lesions, or abnormalities with greater precision and accuracy.

  • Multiple Views: By providing enhanced images of various body regions, CT scans with IV contrast allow healthcare providers to evaluate multiple aspects of a patient's anatomy. This comprehensive evaluation can aid in diagnosing a wide range of medical conditions, from vascular disorders to tumours.

Yes, but there aren't many chances. It carries the same risk of adverse effects as any medicine. The CT scan's contrast agent carries a small risk of an allergic reaction; however, it is uncommon.
