For almost a decade now, Siemens’ Dual Source concept has spearheaded computed tomography imaging and proven its value in exceptional products. During this time, Dual Source CT (DSCT) has continually set new standards in CT imaging. In 2013, the latest pinnacle was reached with the introduction of SOMATOM® Force.
We use Dual Energy CT (DECT) for pulmonary CT angiography in children which enables the evaluation of the pulmonary arteries and lung perfusion from a single contrast-enhanced CT examination.
CARE kV has the advantage of automatically selecting the optimal kV settings to potentially save dose. In cases where the kV needs to remain the same, such as in multiphase studies, scan entries can be grouped easily for constant scan protocols. Learn more from these tips and tricks.
Radiation therapy requires a delicate balance between effectively treating the tumor and limiting the damage to surrounding healthy tissue. Moving tumors like lung cancer often require larger target margins to capture the whole range of motion thus also exposing some organs to unncessary radiation.
A 45-year-old male patient, complaining of progressive shortness of breath, coughing with sputum production and weight loss for the past two years, was referred to a chest physician for checkup. He had worked as a quarryman, without using respiratory protection. A chest CT scan was ordered upon the suspicion of an occupational lung disease.
A 56-year-old male patient, with history of podagra, was complaining of intense pain in the first left metatarsophalangeal joint for the past three days. The serum uric acid test results were normal. Dual Energy (DE) CT was requested for further evaluation.
A 58-year-old male patient, who has been suffering from chronic liver disease with portal hypertension for the past 12 years, presented himself to the hospital due to abdominal distension for the past month. Hepatocellular carcinoma was suspected, and a TwinBeam Dual Energy (TBDE) CT was ordered for assessment.
The relationship between calcium deposition and the development of coronary artery diseases (CAD) has been well-known for decades. In 1990, Arthur Agatston and his colleagues introduced the first practically applicable procedure to quantify calcium in coronary arteries – but the acquisition methods for this quantification have not evolved much since then.
A 7-year-old girl was presented for an evaluation of her small stature when compared to her peers. She was evaluated by an endocrinologist and diagnosed with Turner syndrome. An echocardiography showed a discrete aortic narrowing, consistent with an aortic coarctation. A CT angiography of the chest was performed for further evaluation.
A 43-year-old female patient, complaining of chest tightness and shortness of breath upon exertion, was admitted to our hospital. The symptoms began a year ago and had aggravated over the past 10 days. The patient had a history of hypertension for the past five years.
An 80-year-old male patient, complaining of chest discomfort, shortness of breath and lower limb edema, came to the hospital for a checkup. A Dual Energy (DE) CT angiography (CTA), followed by a dynamic 4D CTA were performed for evaluation.
This year’s ECR is coming up and Siemens Healthineers Computed Tomography will offer two symposia together with Bayer.
Massive carotid body tumor
A 45-year-old female patient, who has had a slow-growing, painless and nonpulsatile mass on the left side of her neck for the past 20 years, was presented to the hospital. She was asymptomatic and her past medical history was unremarkable. A CT angiography (CTA) was requested for pre-operative evaluation. Read more.
