Computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are systems that assist doctors in the interpretation of medical images.Imaging techniques in X-ray, MRI, endoscopy, and ultrasound diagnostics yield a great deal of information that the radiologist or other medical professional has to analyze and evaluate comprehensively in a short time.
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
However, magnetic resonance imaging (MRI) scans are not associated with a radiation risk, and MRI scans are being evaluated for their use in cancer screening. [51] There is a significant risk of detecting incidentalomas - benign lesions that might be misinterpreted as cancer and put patients at potential risk by undergoing unnecessary follow-up ...
A terminally ill woman whose cancer was missed twice by clinicians is calling for a change in the way radiologists assess scans to prevent more patients having a similar experience.
Ultrasound may also detect fetal organ anomaly. Usually scans for this type of detection are done around 18 to 23 weeks of gestational age (called the "anatomy scan", "anomaly scan," or "level 2 ultrasound").
A full-body scan has the potential to identify disease (e.g. cancer) in early stages, and early identification can improve the success of curative efforts. Controversy arises from the use of full-body scans in the screening of patients who have no signs or symptoms suggestive of a disease. [5]
More than 235,000 new cases of lung cancer are expected in the United States in 2021 with approximately 130,000 deaths expected in 2021. [1] In addition, at the time of diagnosis, 57% of lung cancers are discovered in advanced stages (III and IV), meaning they are more widespread or aggressive cancers. [2]
In addition, 3D ultrasound provides surgical guidance in organ transplantation and cancer treatment, especially by employing rotational visualizing during scan. [10] Various methods are used in this area, including rotational scanning, slice projection, and the use of integrated array transducers. [ 11 ]
