If you could read another's heart, what would you want to know? For cardiologists, new imaging technologies provide a way to detect and diagnose heart problems sooner than later. The Biograph TruePoint PET∙CT, as described in Breast Cancer: Looking from the Outside In, is one such bio-imaging system from Siemens Medical Solutions. Simply, the Siemens Biograph offers incredible resolution and quality in order to improve a patient's treatment options. Along with the oncologists who use the Biograph TruePoint PET∙CT, cardiologists can use the device with a PET∙CT Cardiology Engine allowing them to implement a streamlined cardiology workflow.
Biograph Breakdown
It's Biograph breakdown time! How do imaging devices such as the PET CT improve cardiac diagnostics? For starters, features such as the LSO HI-REZ PET offer a 250% improvement in volumetric resolution of scans. Simply put, this gives doctors a better opportunity to detect tiny lesions that were once undetectable. By using a higher light output, the LSO enables the formation of truly tiny detector crystals. The smaller the crystal size, the greater the number of crystals. This finer spatial resolution permits the creation of more image planes, which in turn allows for smaller sampling and enhanced lesion detection.
LSO HI-REZ PET is just one of the Siemens Biograph's defining characteristics. From Pico-3D to True C to 3D Imaging, the Biograph's features and workflow solutions can literally change PET CT imaging. The following chart summarizes these features and provides both descriptions and benefits.
