Summary: CTC and MRC have relatively higher diagnostic value for diagnosing CRC, while PET/CT has higher diagnostic value in detecting local recurrence for patients with CRC.

Summary: A retrospective study with 316,001 individuals revealed that polyps sized 10-20mm and high-grade dysplasia are significantly associated with post-colonoscopy colorectal cancer (PCCRC) mortality. Patients with polyps <10mm and without high-grade dysplasia have significantly lower PCCRC mortality compared to the general population, while those with polyps >10mm or with high-grade dysplasia do not have this advantage.

Summary: CCE shows potential advantages in CRC screening, with comparable accuracy to colonoscopy in detecting CRC and polyps. Its sensitivity is superior to CTC, but improvement is needed in completion rates.

Summary: This article discusses the recommendations for annual screening of lung cancer with chest low-dose CT and screening of colorectal cancer with CT colonography. It also explores the possibility of combining these two screenings in a single CT appointment. The article highlights the importance of Computer Assisted Diagnosis systems and identifies some uncertainties that need to be addressed.

Summary: The study found that there were minimal differences in the performance of CTC and BE in early and advanced cancer groups, but BE may be more accurate in measuring distance from the anal canal's superior margin. CTC may be a viable alternative imaging modality in some cases, but BE should be preferred in cases near the anal canal's anterior wall and in cases after chemoradiation therapy.

Summary: This study investigates the use of an 'electronic biopsy' (EB) technique in computed tomographic colonography (CTC) for further differentiation and 2D image correlation of endoluminal lesions in the air spaces. The study found that EB significantly improves the 3D gray-level presentation for evaluating the surface and inside of endoluminal lesions and achieves better 3D to 2D image correlation compared to other techniques. EB can be used in CTC to improve the differentiation of endoluminal lesions and increase the correlation between 3D and 2D images of the lesions.

Summary: There are multiple screening options for colorectal cancer, each with varying levels of evidence in reducing cancer mortality, detecting cancer or precursor lesions, and risks of harms. This systematic review summarizes published evidence on the benefits and harms of screening for colorectal cancer in asymptomatic, community-dwelling adults to support the 2021 US Preventive Services Task Force Recommendation Statement.

Summary: The study found that in preoperative evaluations of colorectal cancer, the quality of 3D-CTA with CTC images for visualizing blood vessels was significantly greater than that of 3D-CIA, especially for arterial and intramesenteric venous systems. Therefore, 3D-CTA with CTC imaging may be useful in evaluating colorectal cancers.

Summary: In this study, the differentiation of premalignant and benign colorectal polyps detected by CT colonography using deep learning was investigated. The approach enabled the identification of high-risk polyps and the visualization of important image regions for predictions.

Summary: A proposed adaptive learning model is used to integrate multi-scale texture features for polyp classification in computed tomography. By geometrically splitting and hierarchically sorting the features, the model addresses the challenges of feature variation and redundancy, resulting in improved classification performance. Experimental results demonstrate that the proposed model outperforms other methods in terms of classification accuracy.

Summary: In an environment of already largely eliminated patient cost sharing, the release of supportive evidence-based recommendations by a recognized credible body was associated with an immediate increase in computed tomography colonography use for colorectal cancer screening in the privately insured population.

Summary: The study found that in T1-CRC, the horizontal and vertical rigidities observed in barium enema examination are correlated with SM invasion depth. Horizontal rigidity may predict lympho-vascular invasion, aiding in therapeutic decision-making.

Summary: Imaging plays an important role in clinically staging colorectal cancer, with advancements in technology leading to increased utility of imaging techniques. The relationship between colorectal cancer stage and survival differs from that of other cancers, with clinical practice utilizing advanced staging to guide treatment. Emerging imaging techniques show potential to become future staging standards.
