Objectives: To measure the organ dose and calculate effective dose from CTAC acquisitions from four commonly used gamma camera SPECT/CT systems. Method: CTAC dosimetry data was collected using thermoluminescent dosimeters on GE's Infinia Hawkeye four and single slice systems, Siemen's Symbia T6 and the Philips Precedence. Organ and effective dose from the administration of 99m Tc-tetrofosmin an...

Introduction: 99mTc-TRODAT-1 is a promising new radiopharmaceutical with the potential for routine use as the radiopharmaceutical for dopamine transporters scintigraphy as far as its image quality and daily availability are concerned. Here we describe the development of a freeze-dried kit formulation based on the tricine exchange labeling approach for the preparation of this radiopha...

Nuclear medicine is a diagnostic imaging modality that is used to obtain clinical information about most of the major tissues and organs of the body. Diagnostic information is obtained from the way the tissues and organs process radiolabeled compounds (radiopharmaceuticals). The radiopharmaceutical is typically administered to the patient though an intravenous injection. The radiopharmaceutical...

A 35-year-old woman was admitted after a sudden left-arm deficit, which was preceded by 3 weeks of the same transient episodes lasting less than 5 minutes each. She was being treated for menorrhagia with tranexamic acid and was also using oral contraceptives. Three weeks before, she had a Mycoplasma pneumoniae respiratory infection. MRI showed a recent ischemia in the territories of the right m...

In cocktail party listening scenarios, the human brain is able to separate competing speech signals. However, the signal processing implemented by the brain to perform cocktail party listening is not well understood. Here, we trained two separate convolutive autoencoder deep neural networks (DNN) to separate monaural and binaural mixtures of two concurrent speech streams. We then used these DNN...

Recent mobile devices are capable of creating and storing a large amount of multimedia data, but sharing those data with others is still challenging. This paper presents Cocktail, a new gesture-based mobile interaction system that exploits bartenders’ motions. Like a bartender who pours drinks to a glass, a user can pour (transfer) multimedia data to other device. The user can also mix music fi...

Because radiopharmaceuticals are intended for human administration, quality control procedures are essential in ensuring the safety of these preparations. Although extensive quality control procedures are performed by the manufacturer, many radiopharmaceutical preparations are prepared in nuclear medicine departments using kits and short-lived radionuclides including technetium-99m CmTc) and in...

OBJECTIVE Estimation of activity accumulated in tumor and organs is very important in predicting the response of radiopharmaceuticals treatment. In this study, we synthesized (177)Lutetium ((177)Lu)-trastuzumab-iron oxide nanoparticles as a double radiopharmaceutical agent for treatment and better estimation of organ activity in a new way by magnetic resonance imaging (MRI). METHODS (177)Lu-t...
