Images are usually acquired using narrow collimation (<1 mm) and can be retrospectively reconstructed using dedicated 3-dimensional workstations and software. CTA is commonly used in the head and chest in the evaluation of pulmonary emboli, aneurysms, vascular malformations, dissection, bleeding and ischemia.
The diagnosis of appendicitis is largely based on the person's signs and symptoms. [12] In cases where the diagnosis is unclear, close observation, medical imaging, and laboratory tests can be helpful. [4] The two most commonly used imaging tests for diagnosing appendicitis are ultrasound and computed tomography (CT scan). [4]

To better visualize the anatomy, post-processing of the images is common. [54] Most common are multiplanar reconstructions (MPR) and volume rendering. For more complex anatomies and procedures, such as heart valve interventions, a true 3D reconstruction or a 3D print is created based on these CT images to gain a deeper understanding. [62] [63 ...
Primal Pictures is a business established in 1991 that provides 3D graphic renderings of human anatomy, built using real scan data from the Visible Human Project, for use by healthcare students, educators, and medical professionals. It operates the Anatomy.tv online platform. [1]
Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Since the abdomen contains most of the body's vital organs, it can be an indicator of a wide variety of diseases.
Contrast agents are sometimes used in CT scans of the chest to accentuate or enhance the differences in radiopacity between vascularized and less vascularized structures, but a standard chest CT scan is usually non-contrasted (i.e. "plain") and relies on different algorithms to produce various series of digitalized images known as view or "window".
