“…Still, however, early attemps were made to detect 32P in vivo although it is a pure beta-emitter. Early observations showed an increased uptake of the radionuclide in tumours and Low-Beer et al (37) made external measurements of superficial breast tumours showing a 25% increased uptake compared with that of surrounding tissues. 32P was also used t o localize brain tumours at surgery and to detect skin tumours and intraocular tumours (38)(39)(40).…”

“…Inasmuch as benign tumors and other growing tissue also concentrate the isotope, malignancy cannot definitely be distinguished. In some hands, however, as early reported by Low‐Beer (19), the method is useful even in original diagnosis.…”

“…Additionally, methods for localizing focal regions of tumor-avid radiotracers with handheld devices have been developed and tested. For example, miniature Geiger-Müller (G-M) tubes (to detect beta particles) [1][2][3] and scintillation detectors (to detect gamma rays) [4][5][6] have been employed as radiation-sensitive probes to identify cancerous tissue during surgical excisions of tumors. Another application of radiation detectors has been in intra-abdominal procedures.…”

Methods to guide the surgical treatment of cancer utilizing handheld beta-sensitive probes in conjunction with tumor-avid radiopharmaceuticals [such as 18F-fluorodeoxyglucose (FDG)] have previously been developed. These technologies could also potentially be used to assist in minimally invasive techniques for the diagnosis of cancer. The goal of this project is to develop and test a system for performing radionuclide-guided endoscopies. This system (called Endoprobe) has four major subsystems: beta detector, position tracker, endoscope, and user interface. The beta detection unit utilizes two miniaturized solid state detectors to preferentially detect beta particles. The position tracking system allows real-time monitoring of the unit's location. The beta detector and position tracking system's receiver are mounted on the tip of an endoscope. Information from the beta detector and tracking system, in addition to the video signal from the endoscope, are combined and presented to the user via a computer interface. The system was tested in a simulated search for radiotracer-avid areas of esophageal cancer. The search for esophageal cancer was chosen because this type of cancer is often diagnosed with endoscopic procedures and has been reported to have good affinity for FDG. Accumulations of FDG in the normal organs of the abdomen were simulated by an anthropomorphic torso phantom filled with the appropriate amounts of radioactivity. A 1.5- mm-thick gelatin film containing FDG was used to simulate radiotracer uptake in the lining of normal esophagus. Esophageal lesions (both benign and malignant) were simulated by thin disks of gelatin (diameters=3.5-12 mm) containing appropriate concentrations of FDG embedded in the gelatin film simulating normal esophagus. Endoprobe facilitated visual identification and examination of the simulated lesions. The position tracking system permitted the location of the Endoprobe tip to be monitored and plotted in real time on a previously acquired positron emission tomography-computed tomography (PET-CT) image of the phantom. The detection system successfully acquired estimates of the beta flux emitted from areas chosen by the user. Indeed, Endoprobe was able to assist in distinguishing simulated FDG-avid areas as small as 3.5 mm in diameter from normal esophagus (p value <0.025). In addition to FDG, Endoprobe can be used with other positron or electron-emitting radionuclides such as IC or 131I. The next phase of this project will focus on modification of the prototype to make it more suitable for clinical use.
