Computer-assisted detection software has moved beyond its initial applications in mammography imaging and is becoming an essential tool in the diagnosis and management of various types of cancer. At RSNA, vendors are showing systems for film and digital mammography, but the real news extends into other applications. There are new systems for chest and abdominal CT images that not only facilitate lesion detection, but also support workflow by automatically generating measurements of lung and liver lesions. RSNA-goers also can check out a prostate MRI CAD application. Similar to breast MRI CAD, the system helps users efficiently sort through the volume of MRI data to more efficiently diagnose prostate disease.
