A CT scan can detect conditions of the brain, like stroke and vascular dementia. Unexplained persistent headaches, giddiness and epilepsy are evaluated using CT. The images produced by a CT scan provide detailed information about brain tissue and brain structures.
Doctors use chest CT to: examine abnormalities found on chest X-rays; help diagnose the causes of signs or symptoms of chest disease, such as cough, shortness of breath, chest pain, or fever; detect and evaluate the extent of tumors that arise in the chest, or tumors that have spread there from other parts of the body; assess whether tumors are responding to treatment; help plan radiation therapy; evaluate injury to the chest, including the heart, blood vessels, lungs, ribs and spine.
The purpose of a CT scan of the paranasal sinuses is to visualize the possible presence of inflammatory or newly formed tissue in the context of the paranasal cavities. In neoplastic, inflammatory and infectious disorders, a CT scan of the paranasal sinuses is performed to demonstrate bony erosions, osteolytic lesions, and calcifications.
CT scan KUB means Computed Tomography of the Kidneys, Ureters, and Bladder. The scan is helpful in getting images of the urinary system. Common indications include renal stone disease, diagnose and assess infection / tumors of the urinary tract and other causes of abdominal pain.
The abdomen and pelvis contains organs of the gastrointestinal, urinary, endocrine, and reproductive systems. A CT scan of the abdomen may be performed to assess the abdomen and its organs for tumors and other lesions, injuries, intra-abdominal bleeding, infections, unexplained abdominal pain, obstructions, or other conditions, particularly when another type of examination, such as X-ray, ultrasound or physical examination, is not conclusive. A CT scan of the abdomen may also be used to evaluate the effects of treatment on abdominal tumors. Another use of abdominal CT is to provide guidance for biopsies and aspiration or either of the tissue from the abdomen.
A coronary angiogram CT is a scan that records pictures of your heart. Before the pictures are taken, dye is injected into a vein (usually in your arm). The dye highlights any blockages in your coronary arteries, helping to diagnose coronary artery disease. Your doctor may recommend a coronary angiogram CT if you have symptoms of coronary artery disease like: Pain or discomfort in your arms, left shoulder, back, neck, jaw, or stomach; irregular heart beat – arrhythmia; difficulty breathing; excessive sweating; indigestion or heartburn; nausea or vomiting; light-headedness or dizziness. coronary angiogram CT can also be used as a screening tool in high-risk asymptomatic population.
CT virtual colonoscopy, also known as colonography, uses low dose radiation CT scanning to obtain an interior view of the colon (the large intestine). This area is otherwise only seen with a more invasive procedure where the doctor inserts an endoscope into the rectum and passes it through the entire colon. The major reason for performing CT colonography is to screen for polyps or cancers in the large intestine. Polyps are growths that arise from the inner lining of the intestine. A very small number of polyps may grow and turn into cancers.
CT of the neck is a study of the neck region from the skull base (bottom of the head) to the lung apices (top of the chest). There are a variety of indications for this study, based on the structure or pathology of interest. These include (but are not limited to): Parotid or submandibular gland lesion or infection; head and neck cancers; pharyngeal/retropharyngeal or tonsillar abscess; neck mass or abscess; tongue mass or lesion; foreign body in the neck or upper airway; tumors or infections involving the vocal cords.
