Some of the medical imaging procedures that are being used are:
- Plain film or digital X-ray imaging
Traditional plain film X-rays are used to capture images of the body’s internal organs in the region where the problem persists, with the patient being made to wear a leather apron to prevent the other parts of the body being exposed to X-ray radiation. The film X-ray is costly and the chemical development of the film takes time.
Digital X-rays use active matrix flat panels consisting of a detection layer deposited over an active matrix array of thin-film transistors and photodiodes. The high-quality image is instantaneously viewed and reviewed within a short time. Since images are digital, they can be shared with radiology specialists whenever needed. X-rays are also useful for detecting some disease processes in soft tissue.
At Continental Hospitals, numerous digital X-Rays are carried out, which makes it the best hospital for digital X-ray imaging in Hyderabad.
- Magnetic resonance imaging (MRI)
Interventional magnetic resonance imaging is performed under magnetic resonance causes minimal exposure to radiation to both the doctor and the patient. It helps in evaluating the physiological information of the soft tissues inside the body. Some of the conditions measured noninvasively by MRI include diffusion of water within the tissue, collateral blood flow around vascular stenosis (hardening of blood vessels), tissue temperature and other conditions.
- Computed tomography (CT) scans
CT scan produces highly detailed x-rays images of the body and can sometimes produce 3D images of specific areas of the body. Recent advances in CT scans include helical scanning, wide detector arrays, tube current modulation, and iterative image construction.
Ct scans help to determine the causes of the diseases in the body and help with the treatment plans given by the interventional radiologists for organ transplants, gastric bypass, cancer, and other disorders, diseases or injuries.
Continental Hospitals is the best hospital for Computed tomography (CT) scans in Hyderabad.
Continuous X-rays are used to produce real-time moving images of the body. It is used to treat medical procedures such as inserting stents, drainage catheters, orthopedic surgery (to guide joint replacements, fracture treatment), and others.
The doctors at Continental Hospitals are specially trained and have the necessary credentials to use fluoroscopy and hence, Continental Hospitals is considered the best hospital for fluoroscopy in Hyderabad.
- Breast imaging (including mammography, breast ultrasound, breast MRI and digital imaging of the breast)
To identify any breast abnormalities, breast imaging is done by the radiologists to accurately interpret the images and help the attending doctor plan the necessary treatment for the patient. The types of breast imaging are:
- Mammography: use of x-rays to give images of the breast, a 3D mammogram that allows the radiologist to see through dense tissue helps in the diagnosis of early cancer if present.
- Breast ultrasound: use of sound waves to create images of breast tissue. It gives the tissue composition and blood flow in the area of concern in the breast
- Breast MRI: use of magnetic resonance to give 3D detailed and clear images of the breast
- Image-guided breast biopsy: a minimally invasive procedure to remove a sample of breast tissue and checked under a microscope for the presence or absence of cancerous cells
The multidisciplinary teams at Continental Hospitals who have a wide range of experience in their specialties, especially in the field of interventional radiology, oncology and women care, make it the best hospital for breast imaging and mammography in Hyderabad.
- Nuclear medicine procedures (including positron emission tomography [PET] and single-photon emission computed tomography [SPECT] scans)
Nuclear medicine imaging uses small amounts of radioactive materials called radiotracers that are typically injected into the bloodstream, inhaled or swallowed. The tracers are screened on two scanning instruments such as:
- Single Photon Emission Computed Tomography (SPECT)
It is an imaging instrument that provides 3D images of the distribution of the radiotracer molecules in the body by detecting the gamma rays from the tracers. SPECT scans diagnose and track heart disease, detect bone disorders, gall bladder disease, and intestinal bleeding.
- Positron Emission Tomography (PET)
This scanner uses radiopharmaceuticals to give 3D images. The radiotracers decay to give positron which interacts with the electrons in the body destroys each other to produce two photons that move in opposite directions. The PET scanner detects the photons from these tracers. PET scans are used to diagnose cancers
Continental Hospitals have the latest models of the scanning instruments, PET and SPECT, making Continental Hospitals, the best hospital for PET and SPECT scans in Hyderabad.
- Imaging of the colon (including virtual CT colonography and barium enema)
Screening tests of the colon include:
- Virtual colonoscopy uses x-rays and computers to produce two-dimensional or three-dimensional images of the colon (large intestine) and display it on screen. It is used to diagnose diseases of the colon, including cancer, polyps, and diverticulosis (bulging pouches on colon wall).
- Barium enema: A test that is used to examine the large intestine, lower parts of the small intestine and rectum using X-ray. Fluoroscopy, a special kind of X-rays is used to see the organs in motion, is often used during a barium enema. It helps to diagnose problems in the colon and rectum.
- Interventional radiology (both diagnostic and therapeutic procedures using catheters)
Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. Vascular access procedures (for treatment such as dialysis) are performed by an interventional radiologist using ultrasound to access the target vein in the neck and then use x-rays to guide the placement of the catheter so that the tip lies in the central veins near the heart.
A similar placement procedure is adopted for Hickman or Groshong catheter and peripherally inserted central catheter.
Also, interventional radiology uses a catheter to open blocked fallopian tubes without surgery, the procedure is called Fallopian tube catheterization.
- Ultrasonography (using high-frequency waves to produce an image for medical analysis)
Ultrasonography uses high-frequency sound (ultrasound) waves to produce images of internal organs and other tissues.
Ultrasound is used to take pictures of the wrist to confirm the presence or absence of carpal tunnel syndrome (median nerve compression in the wrist).
If carpal tunnel syndrome is present, ultrasound is used to guide the placement of a needle into the carpal tunnel to inject a small dose of corticosteroid (or ‘steroid’) and local anesthetic medication.
