“…Ju et al (36) concluded that EUS is superior to spiral CT for the judgment of tumor infiltrate depth and concluded that neither modality provides a satisfactory assessment of lymph node metastasis for rectal cancer. However, Ahmetoğlu et al (37) showed that multidetector CT can be highly accurate in the prediction of T staging, N staging, International Union Against Cancer (IUCC) staging, and mesorectal fascia involvement in the preoperative local staging of rectal cancer. In contrast to these results, Juchems et al (38) stated that multidetector CT fails to reliably identify IUCC I in rectal cancer patients.…”

20T he prognosis and treatment of rectal carcinoma depends on the tumor stage at presentation (1). Local tumor extent, involved lymph nodes, and the presence of distant metastases are the main factors that influence prognosis (1-5). A poor prognosis of rectal cancer is associated with a high risk of metastases and local recurrence (6). Incomplete removal of the tumor is the major cause of local recurrence, which varies from 3% to 32% (7,8). Total mesorectal excision (TME) is the standard surgical approach in primary rectal cancer. TME involves the removal of the mesorectum, which contains the rectal tumor, all local draining nodes and the mesorectal fat by sharp dissection along the mesorectal fascia (9-12). This minimizes the chance of any tumor being left behind and results in a substantial reduction of the high local recurrence rate to less than 10% (8, 13) even without adjunctive treatment (13,14). When performing TME, knowledge of the relationship of the tumor to the circumferential resection margin (CRM) is important. When the CRM is involved with the tumor, the risk of local recurrence is high (9,(15)(16)(17).Chemoradiation therapy is the standard adjunctive preoperative treatment for patients with a high likelihood of curative resection failure (14,18). According to the recent literature, patients who received preoperative chemoradiation therapy had a lower rate of local recurrence compared to patients who received postoperative chemotherapy and radiation therapy (1,19). Therefore, there is a need for preoperative imaging methods to aid in the identification of patients with extrarectal spread who may benefit from preoperative chemoradiation therapy (20).Magnetic resonance imaging (MRI) is the most promising diagnostic method for the preoperative local staging of rectal cancer (8,21). Spatial resolution has dramatically improved with advances in MRI techniques, such as the use of endorectal and phased-array coils (22,23). Current evidence suggests that MRI is the most accurate technique for predicting tumor stage (24) because it provides an assessment of the local prognostic factors, including the extent of extramural tumor spread, the involvement of the lateral resection margin, the involvement of neighboring organs in the pelvis, the presence of local lymph node metastases, extramural lymphovascular infiltration and peritoneal involvement (9,25,26).The purposes of this study were to evaluate the accuracy of MRI performed with phased-array coil for preoperative local tumor staging in patients with rectal cancer and emphasize the importance of the preoperative differentiation of T2 tumors from T3 so the appropriate treatment plan can be applied. Materials and methods PatientsTwenty-four patients with histopathologically proven primary rectal cancer were prospectively examined using MRI with a phased-array PURPOSEThis study evaluated the accuracy of phased-array magnetic resonance imaging (MRI) for preoperative local tumor staging in primary rectal cancer and emphasized the importance of the preoperativ...

“…Für Fragestellungen, die eine Darstellung der mesorektalen Faszie und die Beziehung des Tumors zu ihr erfordern, weist das MRT aktuell die höchste Sensitivität auf [694]. Das Spiral-CT stellt eine mögliche Alternative dar [688], in der Endosonografie lässt sich die Faszie nicht darstellen.…”

“…ERUS and PET-CT are not accurate in predicting an involvement of the MRF [3,19]. MDCT might represent an alternative method [20], although it has a low diagnostic value in low-seated tumors and especially in those located in the low anterior rectal wall [3]. …”

Background: Radiological imaging plays an important role in the setting of staging, follow-up, and imaging-guided treatment of colorectal carcinoma (CRC). Methods: This review aims to summarize the current state of the art of the different radiological imaging procedures in CRC including an overview over recently published national and European guidelines and consensus statements concerning the imaging of CRC patients. Results and Conclusion: Radiological imaging is widely embedded in national and international guidelines, and structured reporting is recommended.
