First HSI study in the field of pancreatic surgery
Several surgical disciplines have already used HSI, one of the leading new imaging systems, with demonstrable success to detect tissue perfusion. In a recent study by the Leipzig research group led by Ines Gockel, hyperspectral imaging has now been investigated for the first time as a helpful tool for assessing liver and gastric perfusion during pancreatoduodenectomy.

Video paper on precision surgery with HSI
A video paper by Jansen-Winkeln et al. impressively demonstrates how maximum precision can be achieved in rectal cancer by combining robotic surgery with intraoperative neuromonitoring and new imaging technologies such as HSI.

HSI correlates with the conventional Modified Allen's Test (MAT)
In a study of 114 healthy patients, Heimes et al. show that HSI could serve as an additional method for assessing collateral blood flow in the hand prior to invasive procedures involving damage to or removal of the radial artery, since HSI can be used to reliably distinguish between perfusion and occlusion. In this respect, HSI shows a strong correlation to the previous gold standard, the modified Allen's Test (MAT). The authors emphasise the many advantages of HSI technology over visual assessment alone: HSI provides objective, reproducible results without interobserver error, can also be used by non-medical staff and provides visual and measurable feedback.
