OBJECTIVE: The aim of this study was to assess the safety and efficacy of extended liver venous deprivation (eLVD), i.e. combination of right portal vein embolisation and right (accessory right) and middle hepatic vein embolisation before major hepatectomy for future remnant liver (FRL) functional increase. METHODS: eLVD was performed in non-cirrhotic patients referred for major hepatectomy in a context of small FRL (baseline FRL <25% of the total liver volume or FRL function <2...

BACKGROUND: Routine work-up for transarterial radioembolization, based on clinical and laboratory parameters, sometimes fails, resulting in severe hepatotoxicity in up to 5% of patients. Quantitative assessment of the pretreatment liver function and its segmental distribution, using hepatobiliary scintigraphy may improve patient selection and treatment planning. A case series will be presented to illustrate the potential of this technique. Hepatocellular carcinoma patients with cirrhosis (Child-Pugh A and B) underwent hepatobiliary scintigraphy pre- and 3 months post-radioembolization as part of a prospective study protocol, which was prematurely terminated because of limited accrual...

Hepatobiliary scintigraphy is a widely used functional imaging modality for diagnosis of a variety of liver diseases, as well as for detecting biliary tract abnormalities. Neonates or infants with persistent jaundice beyond the physiological period are usually evaluated with hepatobiliary scintigraphy. The authors present a 5-month-old girl with neonatal jaundice, ascites, and umbilical and bilateral inguinal hernias in whom spontaneous rupture of the biliary duct resulted in intraperitoneal bile leak with passage of tracer into bilateral inguinal hernial sacs...

Liver function assessment by hepatocyte-specific contrast-enhanced magnetic resonance imaging is becoming a new biomarker. Liver function can be assessed by T1 mapping (reduction rate) and signal intensity measurement (relative enhancement ratio) before and after GD-EOB-DTPA (gadoxetic acid) administration, as alternative to Tc-99m galactosyl serum albumin scintigraphy, 99m Tc-labeled mebrofenin scintigraphy, and indocyanine green clearance test. Magnetic resonance imaging assessment of liver function can enable diagnosis of cirrhosis, nonalcoholic fatty liver disease associated fibrosis and steatohepatitis, primary sclerosing cholangitis, toxic hepatitis, and chemotherapy and radiotherapy-related changes, which may be only visible on hepatobiliary phase images...

REVIEW
Stephen Thomas, Kayleen Jahangir
Clinical data such as history, physical examination, and laboratory tests are useful in identifying patients with biliary obstruction and biliary sources of infection. However, if intervention is planned, noninvasive imaging is needed to confirm the presence, location, and extent of the disease process. Currently, the most commonly available and used noninvasive modalities are ultrasound (US), computed tomography (CT), magnetic resonance (MR), and nuclear medicine hepatobiliary scintigraphy (HIDA). US is quick, portable, readily available, and is commonly the first imaging modality used when biliary pathology is suspected...

BACKGROUND: Portal vein embolization is the gold standard approach to preoperatively enhance the future liver remnant before liver resection. Portal vein embolization is studied in several experimental animal models; however, clinical translation of results is often difficult. We aimed to examine the translational value of the portal vein embolization response in a standardized rabbit model by comparing the volume and function increase with the response seen in patients. METHODS: Six rabbits were subjected to embolization of the cranial liver lobes, and the hypertrophy response of the caudal liver lobe was studied using computed tomography volumetry and Technetium-99m-labeled-mebrofenin hepatobiliary scintigraphy...

BACKGROUND: We assess the performance of ultrasound (US) and hepatobiliary scintigraphy (HIDA) as confirmatory studies in acute cholecystitis (AC) and demonstrate our current imaging protocol's impact on outcomes. STUDY DESIGN: Between January 2013 to July 2014, 117 patients were admitted through the emergency room with a preliminary diagnosis of AC. Overall, 106/117 (91%) of the patients received US preadmission and 34/117 (29%) received a HIDA post admission. Primary end points included: 1) diagnostic test reliability for AC, and 2) outcome and quality measures (time to surgery, LOS, costs, etc...

BACKGROUND: (99m)Tc-mebrofenin-hepatobiliary-scintigraphy (HBS) enables measurement of future remnant liver (FRL)-function and was implemented in our preoperative routine after calculation of the cut-off value for prediction of postoperative liver failure (LF). This study evaluates our results since the implementation of HBS. Additionally, CT-volumetric methods of FRL-assessment, standardized liver volumetry and FRL/body-weight ratio (FRL-BWR), were evaluated. METHODS: 163 patients who underwent major liver resection were included...

Background and Aims. Biliary complications are the most frequent complications after common liver surgeries. In this study, accuracy of hepatobiliary scintigraphy (HBS) and impact of hyperbilirubinemia were evaluated. Methods. Between November 2007 and February 2016, 131 patients underwent hepatobiliary scintigraphy after having liver surgery. 39 patients with 42 scans after LTX (n = 13) or hepatic resection (n = 26) were evaluated in the study; 27 were male, with mean age 60 years. The subjects underwent hepatobiliary scintigraphy with Tc-99m labeled Mebrofenin...

Iatrogenic and traumatic bile leaks are uncommon. However, given the overall increase in number of hepatobiliary surgeries and the paradigm shift toward nonoperative management of patients with liver trauma, they have become more prevalent in recent years. Imaging is essential to establishing early diagnosis and guiding treatment as the clinical signs and symptoms of bile leaks are nonspecific, and a delay in recognition of bile leaks portends a high morbidity and mortality rate. Findings suspicious for a bile leak at computed tomography or ultrasonography include free or contained peri- or intrahepatic low density fluid in the setting of recent trauma or hepatobiliary surgery...

INTRODUCTION: Age itself is not considered a contraindication for high impact surgery. However, the aging process of the liver remains largely unknown. This study evaluates age-dependent changes in liver function using a quantitative liver function test. METHODS: Between January 2005 and December 2014, 508 patients underwent (99m)Tc-mebrofenin hepatobiliary scintigraphy (HBS) for the assessment of liver function. These included 203 patients with healthy livers (group A) and 57 patients with HCC and Child-Pugh A (group B)...

INTRODUCTION: The aim of this study was to evaluate the validity of (99m)Technetium-trimethylbromo-iminodiacetic acid hepatobiliary scintigraphy (HS) for the diagnosis of biliary atresia (BA). METHODS: From January 2005 to December 2009, a total of 47 infants with conjugated hyperbilirubinaemia (> 20 micromol/l total bilirubin of which 20% is conjugated) underwent HS. BA was suspected if no tracer was visualised in the gut 24 hours post-injection. The results of the HSs were compared with the gold standard, laparotomy with antegrade cholangiography findings...

We report the first known instance of the clinical use of 99mTc-mebrofenin hepatobiliary scintigraphy (HBS) for the optimization of radiotherapy treatment planning and for the follow-up of acute toxicity in a patient undergoing stereotactic body radiation therapy for hepatocellular carcinoma. In our experience, HBS allowed the identification and the sparing of more functioning liver areas, thus potentially reducing the risk of radiation-induced liver toxicity.

INTRODUCTION: Posthepatectomy liver failure (PHLF) is a major complication after hepatectomy with a high mortality rate and is likely to happen in insufficient liver remnant. We hypothesize that assessment of the estimated future liver remnant function (eFLRF), combining future remnant liver volume (FLRV) with total liver function (TLF), is an accurate formula for prediction of PHLF. METHODS: 88 patients undergoing hepatectomy were included. The ratio of the future liver remnant volume (FLRV%) was measured on MRI...

BACKGROUND: Obesity is associated with nonalcoholic fatty liver disease (NAFLD), which is improved by bariatric surgery. Hepatobiliary scintigraphy with 99m.-Tc diisopropylacetanilido iminodiacetic acid (99mTc-DISIDA) has proved to be highly effective for the assessment of bile flow, representing an indirect measurement of hepatocyte and cholangiocyte function. The objective of this study was to assess the effects of Roux-en-Y gastric bypass (RYGB) on bile flow in obese subjects by hepatobiliary scintigraphy...
