As the necrotising effect is achieved with beta-emission from a number of different radio-active isotopes delivered directly into the tumoral lesion, rather than through the traditional intra-arterial route, this treatment is often called "Interstitial Beta-Ablation". The definition "interstitial" is not totally correct, however: a needle large enough to deliver the radio-active isotopes and their

Alternative definitions have been used, such as "parenchymal" and "intratumoral", even if this latter definition is often used also for intra-arterial approaches. Organs other than the liver can be targeted: pancreas, kidney, lung and breast have been considered. The percutaneous route, furthermore, is not the only one used: intra-operatory and peri-endoscopic routes are being investigated, depending on the target organ. Some of the isotopes listed above are pure beta-emitters (Yttrium 90, Phosphorus 32), other (Holmium 166, Rhenium 188) have also a low-energy level of gamma emission. This can be extremely useful for J Liver Res Disord Ther. 2018;4(2):94-95 94
