Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
In most cases, patients with heart metastases have advanced tumour disease, with the heart being only one of the many places involved in the generalised tumour spread. At that stage of the disease, the patients will likely have already undergone extensive chemotherapy, radiation therapy or surgical procedures. Cardiac treatment is usually ...
An Australian study of 10.9 million people reported that the increased incidence of cancer after CT scan exposure in this cohort was mostly due to irradiation. In this group, one in every 1,800 CT scans was followed by an excess cancer. If the lifetime risk of developing cancer is 40% then the absolute risk rises to 40.05% after a CT.
Coronary CT angiography (CCTA) is the use of CT angiography to assess the arteries of the heart. The patient receives an intravenous injection of contrast and then the heart is scanned using a high speed CT scanner. With the advances in CT technology, patients are typically able to be scanned without needing medicines by simply holding their ...
Alcohol and the risk of dying from any cause. Heart disease and cancer are, respectively, the first- and second-leading causes of death in the U.S., but alcohol can increase the risks of dying ...
As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage. [6] An alternative to a full-body CT scan may be Magnetic resonance imaging (MRI) scans. MRI scans are generally more expensive than CT but do not expose the patient to ionizing ...
Superior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum , most commonly lung cancer and non-Hodgkin's lymphoma , directly compressing or invading ...
Over a 45-years span — between 1975 and 2020 — improvements in cancer screenings and prevention strategies have reduced deaths from five common cancers more than any advances in treatments ...
