Computed Tomography Angiography

-

 Computed Tomography Angiography (CTA) is a type of medical imaging exam that uses X-rays and computer technology to create detailed images of blood vessels. It is a non-invasive, fast and highly effective method of visualizing blood flow in various parts of the body.


CTA provides clear images of the blood vessels, including their size, shape, and location, as well as any blockages or abnormalities. This information is essential for diagnosing and treating a variety of conditions, including heart disease, aneurysms, and strokes.

The exam is simple and convenient for patients, as it only requires lying still on a table for a few minutes while the images are taken. The radiation exposure during CTA is low, making it a safe alternative to traditional angiography, which involves injecting a dye into the bloodstream and using X-rays to track its flow.

In addition to its diagnostic capabilities, CTA is also used to monitor the progress of treatments such as stent placement or surgical repairs. This allows doctors to quickly and easily determine the effectiveness of the treatment and make any necessary adjustments.

Overall, CTA is a valuable tool in modern medicine, providing critical information for the diagnosis and treatment of a wide range of medical conditions. With its non-invasive nature and fast, high-quality results, CTA is a popular choice for both patients and doctors alike.

Arrhythmia surgery

  Arrhythmia surgery is a medical procedure performed to treat irregular heartbeats, also known as arrhythmias. These abnormal heart rhythms can cause symptoms such as fatigue, dizziness, shortness of breath, and even chest pain. If left untreated, they can lead to serious complications, such as stroke or heart failure. Arrhythmia surgery is usually recommended when medication and other non-invasive treatments fail to control the irregular heartbeats. The procedure involves the use of various techniques to destroy or modify the abnormal electrical pathways in the heart. Some of the techniques used in arrhythmia surgery include catheter ablation, maze procedure, and implantable devices such as pacemakers and defibrillators. Catheter ablation is a minimally invasive procedure in which a thin, flexible tube (catheter) is inserted through a vein in the groin and threaded up to the heart. Once in the heart, the catheter is used to deliver energy (such as radiofrequency or cryotherapy)...

As far as treatment for cancer goes, with recent technology and advanced methods of treating the disease the procedure has of course become a lot less painful and efficient, decreasing mortality rate by quite a lot as compared to traditional methods of treatment. Doctors now have a better understanding of the causes, symptoms and effects and how to treat their patients accurately. The patients too are always updated and consoled to the best one can, but does it mean that those affected are free of mental and emotional distress? Unfortunately the answer is still a no for this one. Knowing that one has ‘cancer’, irrespective of the sort and the intensity, the word itself has the capability to put a person into deep distress.

No matter how much knowledge and sympathy or compassion one might ge...

Biopsies A biopsy is a procedure that takes cell samples for a pathologist to look at in a lab. A lymph node biopsy, which involves taking a sample of lymph tissue or the entire lymph node, may be required for certain types of blood cancer, such as lymphoma. Certain types of blood cancer can be identified by testing your bone marrow, the place where blood cells are made. A bone marrow aspiration is a method by which a small amount of blood, bone, and bone are taken from either a breast...
