title: SEOM/SERAM consensus statement on radiological diagnosis, response assessment and follow-up in colorectal cancer.
abstract: Colorectal cancer (CRC) is one of the world's most common cancers, and has one of the highest mortality rates. The last few decades have seen great progress in preventing, diagnosing and treating this disease, providing undeniable impact on patients' prognosis and quality of life. At all these stages of CRC management, imaging techniques play an essential role. This article reviews some important issues concerning the use of various radiological techniques in the screening, diagnosis, staging, assessment of treatment response, and follow-up of patients with CRC. It also includes a number of practical recommendations on indications for use, technical requirements, minimum information required in the radiology report, evaluation criteria for the response to various drugs, and the recommended frequency at which different examinations should be performed. This consensus statement is the result of cooperation between the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Radiology (SERAM).
