“…After cross‐referencing the references, 11 extra studies were included, thus reaching a total number of 76. After revision, 51 studies were excluded for the following reasons: 23 because including mixed samples (i.e., including also patients with metastases from tumors other than CRC) (16–38), 12 because not comparative or assessing less than two eligible modalities (39–50), 5 because not having an adequate reference standard (51–55), 4 because review (56–59), 6 because with a different aim (60–65), and 1 because on duplicated patients in other included study (66). Therefore, 25 (5, 67–90) studies fulfilled eligibility criteria and were, therefore, selected for data extraction and analysis.…”

Surgery of liver metastases can be effective, and the appropriate selection of surgical candidates relies first on imaging. Different techniques are available, but information on their relative performance is unclear. The aim of this overview is to assess the imaging modality performance in the diagnosis of colorectal cancer (CRC) liver metastases. MEDLINE and EMBASE were searched for articles published from January 2000 to August 2008. Eligible trials had to be conducted on patients with diagnosis/suspicion of CRC liver metastases, comparing more than two modalities among MRI, computed tomography (CT), positron emission tomography using fluoro-18-deoxyglucose (FDG-PET), ultrasonography (US). Pooled estimates of sensitivity, specificity were calculated and pairwise comparisons were performed. Of 6030 screened articles, 25 were eligible. Sensitivity and specificity on a per-patient basis for US, CT, MRI, and FDG-PET were 63.0% and 97.6%, 74.8% and 95.6%, 81.1% and 97.2, and 93.8% and 98.7%, respectively. On a per-lesion basis, sensitivity was 86.3%, 82.6%, 86.3%, and 86.0%, respectively. Specificity was reported in few studies. MRI showed a better sensitivity than CT in per-patient (odds ratio [OR]: 0.69; 95% confidence interval [CI]: 0.47-0.99; P ¼ 0.05) and in per-lesion analysis (OR: 0.66; 95% CI: 0.55-0.80; P < 0.0001). In per-lesion analysis, the difference was higher when liver-specific contrast agents were administered. Available evidence supports the MRI use for the detection of CRC liver metastases. SURGICAL TREATMENT OF colorectal cancer (CRC) liver metastases is the only treatment associated with demonstrated long-term survival (1). Patients with untreated but potentially resectable metastases show a median survival of 6 to 12 months (2), while 5-year survival rate of 45-60% can be achieved in appropriate selected patients (3) and this selection relies first on imaging. Although in the past 20 years the role of diagnostic imaging has gained an increasing importance, due to a rapid improvement both in imaging technology and in its clinical application, no consensus has yet emerged on the optimal imaging strategy for the preoperative staging of patients with CRC liver metastases (3). Moreover, after preoperative imaging, intraoperative ultrasonography (IOUS) has been reported to identify at least one additional lesion in 10-12% of cases (4). These data indicate that intensive efforts should be used to improve staging to avoid unnecessary laparotomy and nontherapeutic resection procedures, especially because nowadays resection of liver metastases is pursued with increasing aggressiveness.The diagnostic value of ultrasound with contrast agents, multi-detector computed tomography (MDCT), and MRI with extra-cellular contrast media (ECCM) and liver-specific contrast media (LSCM) is debated. Nowadays MDCT is the mainstay of staging and follow-up of these patients, because it provides good coverage of the liver and the complete abdomen and chest in one session. MRI has been shown to be also useful in the preope...

“…ERUS can also detect bulky tumours of the anterior rectal wall, which can obstruct the vaginal canal, complicating delivery. While CT is the standard staging method in non-pregnant CRC patients, in pregnancy MRI is preferred as it does not expose the foetus to ionizing radiation and has a similar accuracy to CT in the diagnosis of CRC [14]. Recent guidelines on MRI, during pregnancy, state that abdominopelvic MRI can be safely used, regardless of GA [15].…”

“…Presently, CT and MR imaging are the mainstay for detection and characterization of liver tumors 21-27. It has been reported that contrast-enhanced MR imaging is more sensitive in detecting and more useful in characterizing focal hepatic lesions than CT 28-31. However, there is a growing interest in the role of DWI in characterizing hepatic lesions.…”

Purpose-To evaluate the role of diffusion-weighted imaging in differentiating between hepatic hemangiomas, both typical and atypical, and other hypervascular liver lesions.Methods-Retrospective review of 182 hypervascular liver lesions in 117 patients was performed. Diffusion and contrast-enhanced magnetic resonance imaging were performed using a 1.5-T unit. Imaging protocol consisted of T 2 -weighted fast spin-echo images, breath-hold diffusion-weighted echo-planar images, and breath-hold unenhanced and contrast-enhanced T 1 -weighted 3-dimensional fat-suppressed spoiled gradient-echo images in the arterial phase (20 seconds) and portal venous phase (60 seconds). Signal intensity changes and apparent diffusion coefficient (ADC) values were evaluated for all lesions. Unpaired t test was used to compare the mean ADC values for different lesions, and statistical significance was set at P < 0.01. Receiver operating characteristic analysis was used to determine the accuracy of diffusion-weighted imaging in differentiating hemangiomas from other hypervascular liver lesions.Results-Lesions included typical and atypical hemangioma (n = 38), hepatocellular carcinoma (HCC; n = 58), focal nodular hyperplasia (FNH; n = 22), and neuroendocrine tumor metastasis (NET; n = 64) with a mean tumor size of 5.3 cm. Mean ADC value for hemangioma, HCC, FNH, and NET was 2.29 × 10 -3 , 1.55 × 10 -3 , 1.65 × 10 -3 , and 1.43 × 10 -3 mm 2 /s, respectively. There was a statistically significant difference in the ADC value of hemangioma compared with that of FNH (P < 0.001), HCC (P < 0.001), and NET (P < 0.001), respectively. The area under the receiver operating characteristic curve was 0.91.Conclusions-Diffusion-weighted magnetic resonance imaging and ADC maps can provide rapid quantifiable information to differentiate typical and atypical hemangiomas from other hypervascular liver lesions.
