This paper focuses on the optimization of MRI-DWI protocols for rectal carcinoma to enhance diagnostic accuracy and improve patient outcomes. Key considerations include optimizing magnet strength, b-value selection, and minimizing artifacts while achieving high signal-to-noise ratio (SNR). Pre-imaging preparations, such as bowel preparation and patient positioning, are highlighted to ensure clear visualization of rectal anatomy. The incorporation of advanced post-processing techniques like apparent diffusion coefficient (ADC) map interpretation provides additional insight into tumor biology, offering potential prognostic value.
