Whole-body low-dose computed tomography and advanced imaging techniques for multiple myeloma bone disease.

Detection of lytic bone lesions is crucial in the workup for multiple myeloma and very often dictates the decision to start treatment. Conventional radiography, despite decades of use, is often insufficient for detection of bone disease in multiple myeloma. Modern imaging techniques such as MRI, PET, and CT offer superior detection of myeloma bone disease and extramedullary manifestations of pl...

Uncertainties in effective dose estimation for CT transmission scan in total body PET-CT imaging with Auto mA3D tube current modulation

Background: Positron Emission Tomography-Computed Tomography (PET-CT) is a useful hybrid imaging modality in the diagnosis of various malignancies. This modality imposes almost 20 mSv radiation dose to the patient. The purpose of the present study was to evaluate the uncertainties in calculated CT effective dose in TUBE CURRENT MODULATION-activated scans by Impact-Dose software.  Materials and ...

Weight-based, low-dose pediatric whole-body PET/CT protocols.

UNLABELLED Adult PET/CT acquisition protocols need to be modified for pediatric imaging to minimize the radiation dose while maintaining diagnostic utility. We developed pediatric PET/CT acquisition protocols customized to patient weight and estimated the dosimetry and cancer risk of these low-dose protocols to communicate basic imaging risks. METHODS Protocols were developed for whole-body (...

Diode calibration for dose determination in total body irradiation

Background: Total Body Irradiation (TBI) is different from standard radiotherapy in many aspects, so it is not easy to predict the delivered dose to the patient under TBI treatment. Diode dosimetry procedures for surface dose reading can help to define variations of the actually delivered dose from the prescribed one. The aim of this study was to describe the measurements made to calib...

Measurement of organ dose in chest CT examination using Monte Carlo simulation

Background: Exposure conditions in CT examinations are quite different from conventional Xray. In CT examination higher dose is given to patient in comparison with the dose in other diagnostic examinations. In order to calculate organ effective dose in chest CT, Monte Carlo simulation has been used in this study. Materials and Methods: The Impact survey data were used to determine the ...
