MRI T1 Relaxation Time in Rectal Cancer

MRI T1 Relaxation Times in Evaluating Neoadjuvant Treatment of Rectal Cancer

The goal of this observational study is to learn about the T1 relaxation time and T1 relaxation time properties of the disease in people with locally advanced rectal cancer. The main question it aims to answer is:

Does MRI T1 relaxation time have a high diagnostic performance in recognizing fibrosis as a complete response to neoadjuvant treatment of rectal cancer?

Participants will receive standard neoadjuvant treatment and be part of the standard examination programme regarding rectal cancer.

Inclusion Criteria:

• rectal cancer, age >18 years

Exclusion Criteria:

• contraindications for MRI (pacemaker, claustrophobia, implanted medical injectors and nerve stimulators),
• previous radiochemotherapy or another disease which investigator judges inappropriate for the persons continued participation.
