About this study
Official title: Diffusion-weighted Imaging Magnetic Resonance for Assessing Liver Fibrosis in Patients With Chronic Viral Hepatitis
Several noninvasive radiological techniques have been investigated for the diagnosis of liver fibrosis and cirrhosis among patients with chronic infection with hepatitis B virus or hepatitis C virus. Diffusion-weighted magnetic resonance imaging (DW-MRI) is a particularly appealing method for the diagnosis of liver fibrosis. The aims of this study are to evaluate the accuracy of DW-MRI in patients with chronic viral hepatitis for determining the stage of liver fibrosis.
Read the detailed description
Among patients with chronic infection with hepatitis B virus or hepatitis C virus, evaluation of the stage of liver fibrosis is of major importance for determining prognosis and therapeutic decisions. Liver biopsy is a costly and invasive technique with associated mortality and morbidity. A typical biopsy fragment represents only 1/50,000 of the organ. Several noninvasive radiological techniques have been investigated for the diagnosis of liver fibrosis and cirrhosis. Diffusion-weighted magnetic resonance imaging (DW-MRI) is a particularly appealing method for the diagnosis of liver fibrosis. Because it is easy to implement, non-operator dependent, and process without the need for contrast agents. However, preliminary studies on small numbers of patients in which various hardware and sequencing profiles were used have reported inconsistent results for staging liver fibrosis with DW-MRI. The aims of this study are to evaluate correlation between stage of hepatic fibrosis and liver apparent diffusion coefficient (ADC) and normalized liver ADC with spleen assessed by DW-MRI in patients with chronic viral hepatitis B or C. Also, this study aim to evaluate factors that influence liver ADC and normalized liver ADC with spleen value for predicting the stage of liver fibrosis as well as to estimate the optimal cutoff values of DW-MRI for determining significant liver fibrosis (fibrosis stage ≥2) and advanced fibrosis (fibrosis stage ≥3).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Diffusion-weighted magnetic resonance imaging (DW-MRI)Device
Magnetic resonance (MR) imaging examination of liver will be performed on a 3.0T Achieva MR scanner (Philips Medical Systems, The Netherlands). Diffusion-weighted imaging (DWI) will be performed using a single-shot echo-planar imaging during a single end expiratory breath-hold. A single observer placed circular regions of interest around 2.30 cm2 to measure mean signal intensity (SI) in the right hepatic lobe and the spleen for each b value, avoiding areas of artifact, vessels, and focal lesions. A monoexponential fit will be performed to calculate liver and spleen apparent diffusion coefficient (ADC) on the basis of ln(SI) as a function of b value, using all b values. Normalized liver ADC will be calculated as the ratio of liver ADC to spleen ADC.

Questions about this trial
What is this clinical trial studying?
A study testing Diffusion-weighted magnetic resonance imaging (DW-MRI) in people with Fibrosis, Liver, run by Mahidol University at 1 site in Thailand.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The correlation coefficient of the stage of hepatic fibrosis and liver apparent diffusion coefficient as assessed by DW-MRI (time frame: At enrollment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02682108, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2016.
