Mangafodipir trisodium injection (Mn-DPDP). A contrast agent for abdominal MR imaging
Magn Reson Imaging Clin N Am 1996 Feb;4(1):73-85.8673718
Mangafodipir trisodium (Mn-DPDP) is one of several recently developed targeted hepatobiliary agents. Contrast-to-noise measurements have shown favorable results for Mn-DPDP-enhanced MR as compared with nonenhanced T1- and T2-weighted images. An improved capability for lesion detection and the ability to characterize tumors of hepatocellular origin have been demonstrated. The prolonged enhancement obtained with Mn-DPDP provides an extended window of time during which effective contrast is maintained as compared with traditional extracellular contrast agents. This report details the experimental and initial clinical experience with Mn-DPDP-enhanced MR imaging of the abdomen.
[Mangafodipir trisodium-enhanced magnetic resonance cholangiography for detection of bile leaks]
J Radiol 2006 Jan;87(1):41-7.16415779 10.1016/s0221-0363(06)73968-3
Purpose: To assess the value of contrast-enhanced magnetic resonance cholangiography with Teslascan perfusion for the detection and localization of trauma-induced and postoperative bile leaks. Materials and methods: Between October 2002 and December 2004, 7 patients with suspected bile duct leaks after trauma (n = 2) or surgery (n = 5) requiring morphological evaluation were included. MRI examination included single shot fast spin- echo T2 weighted and gradient echo T1 weighted images prior to and 112 minutes in average after IV administration of Mangafodipir trisodium. The results of contrast enhanced MR cholangiography were correlated to surgery (n = 3), clinical course (n = 3) and percutaneous drainage (n = 1). Results: Mangafodipir trisodium-enhanced imaging showed extravasated Teslascan in collections in 6 patients (86%) whereas the combination of T2 weighted images and Mangafodipir trisodium enhanced images revealed biliary collections in 7 patients (100%). The fistula between bile duct and collection was visualized in 4 patients (57%) before Mangafodipir trisodium perfusion and in 3 patients (43%) after injection. In one patient the fistula was visible only after injection. Combination of both pre- and post injection MR correctly depicted the origin of bile leak in 5 cases (71%). Conclusion: Mangafodipir trisodium-enhanced magnetic resonance cholangiography is a non invasive technique that can successfully detect the presence of bile duct leaks. The combination of T2 weighted MR cholangiography and mangafodipir trisodium-enhanced T1 weighted MR cholangiography increases the sensitivity in detection and localization of the site of bile leak.
MRI with Mangafodipir trisodium in the detection and staging of pancreatic cancer
J Magn Reson Imaging 2000 Aug;12(2):261-8.10931589 10.1002/1522-2586(200008)12:2<261::aid-jmri8>3.0.co;2-r
The purpose of this study was to compare prospectively computed tomography (CT) and magnetic resonance (MR) imaging before and after Mangafodipir trisodium infusion for the detection and staging of focal pancreatic lesions. From November 1996 to October 1997, 43 consecutive patients suspected to have a focal pancreatic lesion were included in a phase III study. Triphasic helical CT was performed, as well as MRI at 1.5 T, as follows: axial T1-weighted (T1w) turbo spin echo (TSE), spectral presaturation with inversion recovery (SPIR) T1w TSE, T1w turbo field echo (TFE), and SPIR T2w TSE before and after Mangafodipir trisodium (0.01 mmol/ml, 0.5 ml/kg) infusion. Imaging results were correlated with surgery, laparoscopy, laparoscopic ultrasound, and biopsy. Objective measurements were performed by measuring signal intensities (SIs) of lesion and parenchyma and calculating contrast indexes (CIs) and contrast-to-noise-ratios (CNRs) to assess the delineation of the tumor. SIs were correlated with four phantom standards with a known SI. Thirty-eight pancreatic adenocarcinomas were present, as well as one cystadenoma, two papillomas, and two cases of focal pancreatitis. SI measurements revealed significant increases in CIs for the lesion compared with the parenchyma in T1w TSE (69.7 vs 152.7; P = 0. 0003) and T1w TFE (107.8 vs 194.2; P = 0.0002). These series also revealed significant increases in CNRs (for T1w TSE: 9.7 vs 13.0; P = 0.0407 and for T1w TFE: 14.5 vs 26.1; P = 0.0001). In the other series, there was no significant increase. CT detected 38 lesions, MRI without Mangafodipir trisodium detected 39 lesions, and MRI with Mangafodipir trisodium detected 40 lesions, giving detection accuracy rates of 88%, 91%, and 93%, respectively. Staging accuracy rates for vascular ingrowth were 81%, 75%, and 81%, respectively. Overall staging accuracy rates were 57%, 54%, and 54%, respectively, mostly due to undetected small metastases in the peritoneum, omentum, or liver (< 1 cm). This study indicates that a) MRI after Mangafodipir trisodium gives a better delineation of the tumor in T1w series, but b) does not significantly improve the detection rate and staging accuracy of focal pancreatic lesions over MRI without this contrast medium.
Safety and efficacy of Mangafodipir trisodium in patients with liver lesions and cirrhosis
Eur Radiol 2003 Jul;13(7):1685-92.12835986 10.1007/s00330-002-1784-5
Mangafodipir trisodium (Mn-DPDP, Teslascan) is a well-tolerated liver contrast agent. Although the enhancement characteristics of the cirrhotic liver after Mangafodipir trisodium administration have been studied, at present there is no published data on the impact that cirrhosis might have on the safety and efficacy profiles of this agent. Our objective is to evaluate by means of a retrospective comparison the safety and efficacy of Mangafodipir trisodium in patients with underlying cirrhosis who were examined for suspicion of focal liver lesions. A total of 923 patients received Mangafodipir trisodium (5 micromol/kg) in 11 prospective randomized European clinical trials. Adverse events and discomfort were recorded and graded in all patients. The efficacy analyses were performed on the subsets consisting of 617 patients with independent lesion counts (detection), and on the subset with 399 patients with independent and onsite final lesion diagnosis (characterization). Of the 399 patients, 149 had histologic confirmation. One hundred eighty of 923 patients (19.5%) had cirrhosis. There were no main differences between cirrhotic and non-cirrhotic patients. Adverse events were observed in 64 patients (6.9%), 6.7% in the cirrhotic group and 7.0% in the non-cirrhotic group, a non-significant difference. Adverse events in most patients were mild or moderate. The presence and intensity of the events did not differ between groups. Discomfort was recorded in 79 patients (8.6%), equally distributed in cirrhotic (6.1%) and non-cirrhotic (9.2%) patients. Regarding lesion count, significantly more lesions were found in the post- than in the precontrast images in both the cirrhotic and non-cirrhotic groups ( p<0.0001). This increase was not influenced by the presence of liver cirrhosis ( p=0.94). Lesion characterization was significantly improved in cirrhotic patients after administration of Mangafodipir trisodium ( p=0.002) but not in non-cirrhotic patients ( p=0.13). Mangafodipir trisodium is a safe and well-tolerated useful contrast agent in patients with cirrhosis.
Characterization of focal liver lesions: use of Mangafodipir trisodium (MnDPDP)-enhanced MR images
Turk J Gastroenterol 2006 Sep;17(3):164-71.16941248
Background/aims: We evaluated the characterization and detection of liver lesions using Mangafodipir trisodium. Methods: A total of 51 patients with liver lesions [13 hepatocellular carcinomas, 18 metastases, 14 hemangiomas, three cholangiocellular carcinomas, two hydatic cysts, and one focal nodular hyperplasia (FNH)] were examined by unenhanced and mangafodipir trisodium-enhanced MRI. Results: After administration of Mangafodipir trisodium by slow intravenous infusion, mangafodipir trisodium-enhanced MRI was performed at 15-30 min and 24 h. The enhancement appeared in normal liver parenchyma and all of the hepatocellular lesions (HCCs and FNH). The lesions in hepatocellular carcinomas patients showed a non-homogeneous enhancement pattern. Non-hepatocellular lesions (hemangiomas, metastases, CCCs) had no enhancement on mangafodipir trisodium-enhanced MRI examinations. The rim-like enhancement pattern was demonstrated in all patients with cholangiocellular carcinomas, and in 14 metastases and 11 hemangiomas. Conclusions: Mangafodipir trisodium-enhanced MRI permits reliable distinction between hepatocellular and non-hepatocellular tumors. Mangafodipir trisodium-enhanced MRI can show more functional and morphologic features of hepatocellular lesions. Some non-hepatocellular lesions which went undetected on unenhanced MRI were visualized after contrast enhancement of the liver. The rim-like enhancement pattern is not specific for metastases. Mangafodipir trisodium-enhanced MRI is safe and well tolerated and may aid in noninvasive diagnosis of liver lesions.
