The diagnostic performance of a simulated “short” gadoxetic acid-enhanced MRI protocol is similar to that of a conventional protocol for the detection of colorectal liver metastases

Abbreviated Gadoxetic Acid‐Enhanced MRI for the Detection of Liver Metastases in Patients With Potentially Resectable Pancreatic Ductal Adenocarcinoma

“…In previous studies with a similar design including patients with colorectal cancer and neuroendocrine tumors, abbreviated MRI protocols that included T2W, DW, and HBP images were highly accurate for the detection and characterization of liver metastases. [7][8][9] Similar results have also been reported for the detection of hepatocellular carcinomas, [19][20][21][22] further supporting the effectiveness of abbreviated MRI protocols. The nonsignificant difference in FOM, sensitivity, and PPV between abbreviated MRI and standard MRI protocols is probably due to the inclusion of DW and HBP images.…”

“…with 19, 15, and 14 years of experience in abdominal imaging, respectively) independently reviewed the following three image sets to detect liver metastases: set 1, CECT consisting of unenhanced, pancreatic, portal venous, and equilibrium phase images; set 2, the combination of CECT and abbreviated gadoxetic acid‐enhanced MRI consisting of fat‐suppressed T2W, DW, and HBP images; and set 3, the combination of CECT and the standard gadoxetic acid‐enhanced MRI consisting of all acquired sequence images. The abbreviated protocol followed previous studies which have reported that the protocol was highly accurate for the diagnosis of liver metastases from colorectal cancer 7,9 . The abbreviated MRI protocol was simulated by extracting the three sequences from the standard MRI protocol.…”

“…The abbreviated protocol followed previous studies which have reported that the protocol was highly accurate for the diagnosis of liver metastases from colorectal cancer. 7,9 The abbreviated MRI protocol was simulated by extracting the three sequences from the standard MRI protocol. Thus, the total examination time of the abbreviated MRI protocol was estimated as less than 10 minutes, while the standard MRI protocol took more than 30 minutes to be completed.…”

“…Abbreviated MRI protocols with limited sequences, which can theoretically be performed in a shorter examination time than the conventional protocols, could be a solution to this problem. Abbreviated MRI protocols that include T2‐weighted (T2W), diffusion‐weighted (DW), and HBP images have been recently shown to be highly accurate for the detection and characterization of liver metastases from colorectal cancer and neuroendocrine tumors 7–9 . Abbreviated MRI protocols may improve the throughput and availability of MRI examinations without compromising the diagnostic performance, which would help in the initial workup and accurate decision‐making regarding the therapeutic strategy for patients with PDAC.…”

The Role of Percutaneous Ablation in the Management of Colorectal Cancer Liver Metastatic Disease

“…Apart from the diagnostic and staging information, the pre-contrast CT scan of the liver resembles tumor visualization on ablation day and provides information on the potential need for pre-ablation contrast medium injection, image fusion system, or any other specific guidance or navigation needs [9]. MRI with diffusion and dynamic post-contrast medium sequences is an excellent imaging technique for detecting liver lesions of small size (as small as 3-4 mm of diameter); in particular, gadoxetate disodium (gadolinium EOB DTPA, Gd-EOB-DTPA, and gadoxetic acid) is a hepato-specific paramagnetic gadolinium-based contrast agent recommended in CLM [23]. Gadolinium-EOB-enhanced MRI is the most sensitive technique to assess liver metastatic disease, and in many centers, this liver-specific MRI constitutes the technique of choice for evaluation of CLM patients.…”
