Gated SPECT

Gated SPECT ko karallaagal ƴeewndo safaara nukliyeer, ko ɓuri heewde ko wonande ɓernde e ƴeewndo perfusion miokardi. Elektrokardiyogram (ECG) ina ardoo keɓgol natal ngal, tawa kadi ko ngalɗoo natal (SPECT) ngal ƴettata ngal, ina hollita ɓernde no nde ɓuuɓtortoo e nder hakkundeere ummoraade e ɓuuɓol R gootol haa e ɓuuɓol goɗɗol ngol.
