Magnetic Relaxation Measurements of Ex Vivo Human Liver Specimens Using a SERF Magnetometer
Reliable assessment of liver iron concentration (LIC) is important for diagnosing and monitoring iron overload disorders. We used a spin exchange relaxation free (SERF) atomic magnetometer to record magnetic relaxation signals from resected human liver tissue. A total of 23 specimens from 20 patients, including normal, fatty, cirrhotic, and hepatocellular carcinoma (HCC) liver, were polarized with a Helmholtz coil inside a magnetic shield, and the field decay after switch off was recorded. For each specimen, a water-referenced, mass-normalized relaxation amplitude ΔB (pT/g) was derived. ΔB was compared with the HISTO-derived water transverse relaxation rates, , from the patients’ clinical MRI. For HCC, SERF measurements were made on resected tumor tissue, whereas MRI sampled non-cancerous liver parenchyma in the same patient. Within each category, ΔB increased with and rank order agreed fully in three of the four categories. Slope differences between categories were significant with conventional standard errors but not with heteroscedasticity-consistent (HC3) standard errors and are therefore regarded as exploratory. These measurements establish a SERF workflow for comparing post-polarization magnetic relaxation amplitudes across resected human liver specimens.- 7 November 2026

A novel simple intra-corporeal Pringle maneuver for laparoscopic hemihepatectomy: how we do it
Introduction To prevent and control hemorrhage is the key to successfully perform laparoscopic hemihepatectomy (LHH). Pringle’s maneuver (PM) is the standard hepatic inflow occlusion technique. Our study was to describe a novel simple way to perform totally intra-corporeal laparoscopic PM and to explore the feasibility of combining PM and selective hemihepatic vascular occlusion technique in LHH. Methods We extracted and analyzed the data of patients who consecutively underwent LHH to validate this new surgery technique. Between January, 2016 and December, 2017, 34 patients were included. Data of pre-operation, operation and post-operation were collected, including some demographic data, operative time, operative blood loss, transfusion rate, hepatic hilum occlusion rate and time, pathologic results, short-term complication, and postoperative hospitalization days. Results Only one patient (3.0%) in our series required conversion to laparotomy as a result of the severe adhesion. The average operative time was 216.9 ± 60.3 min. The mean hepatic inflow occlusion time was 25.3 ± 14.5 min. The average estimated blood loss was 192.9 ± 152.2 ml. All patients received R0 resection. Conclusion The novel hepatic inflow occlusion device is a safe reliable and convenient technique for LHH that is associated with favorable perioperative outcomes and low risk of conversion.
