An algorithm that could quickly pull standard measurements around the aorta would greatly improve radiology practices, especially those that see a lot of patients for aorta aneurysms. These measurements include aortic root, sinotubular junction, mid-ascending, distal ascending, mid-arch, prox. descending, mid descending, diaphragm and celiac origin.
This algorithm would also add value to health care in decreasing variance of these measurements and allowing clinicians to more effectively track changes in these structures over time. Standards on the locales of the aorta and obliquity for a true perpendicular measurement would improve the way radiologists read and report this information.
Patient has a chest radiograph or a chest CT scan done for other reasons, demonstrating a thoracic aortic aneurysm. Algorithm is triggered and returns measurements on the aortic root, sinotubular junction, mid-ascending, distal ascending, mid-arch, prox. descending, mid descending, diaphragm and celiac origin. The measurements are done perpendicular to the aorta at each location taking into account the tortuosity. Radiologist verifies the values and submits the report which impact treatment. These metrics are then compared later in time on followup examinations to monitor the aneurysm dimensional stability. The goal is to assure that followup examinations are handled in an identical manner, measuring diameters at the same locales and with the same perpendicular orientation to the long axis of the aorta to facilitate accurate comparison.
Patient receives CT examination. The image is obtained from modality and sent to PACS and the AI engine. The image is analyzed by the engine. The system then measures the aortic root, sinotubular junction , mid-ascending, distal ascending, mid-arch, prox. descending, mid descending, diaphragm and celiac origin. An alert message is sent to PACS from the engine with the information.
