A positron emission tomography (PET) tracer composed of (18)F-labeled maltohexaose (MH(18)F) can image bacteria in vivo with a sensitivity and specificity that are orders of magnitude higher than those of fluorodeoxyglucose ((18)FDG). MH(18)F can detect early-stage infections composed of as few as 10(5) E. coli colony-forming units (CFUs), and can identify drug resistance in bacteria in vivo. MH(18)F has the potential to improve the diagnosis of bacterial infections given its unique combination of high specificity and sensitivity for bacteria.
一种由¹⁸F标记的麦芽六糖（MH¹⁸F）组成的正电子发射断层扫描（PET）示踪剂能够在体内对细菌进行成像，其灵敏度和特异性比氟脱氧葡萄糖（¹⁸FDG）高几个数量级。MH¹⁸F能够检测出仅由10⁵个大肠杆菌菌落形成单位（CFU）组成的早期感染，并能在体内识别细菌的耐药性。鉴于MH¹⁸F对细菌具有高特异性和高灵敏度的独特组合，它有潜力改善细菌感染的诊断。
