Whole-Body Imaging Modalities in Oncology
This article outlines the expanding approaches to whole-body imaging in oncology focusing on whole-body MRI and comparing it to emerging applications of whole-body CT, scintigraphy, and above all PET CT imaging. Whole-body MRI is widely available, non-ionizing and rapidly acquired, and inexpensive relative to PET CT. While it has many advantages, WBMRI is non-specific and, when compared to PET CT, is less sensitive. This article expands each of these issues comparing individual modalities as they refer to specific cancers.[...]© Thieme Medical PublishersGet connected:Table of contents | Abstract | Full text (Source: Seminars in Musculoskeletal Radiology)...

The Role of Whole-Body Imaging in the Diagnosis, Staging, and Follow-Up of Multiple Myeloma
Semin Musculoskelet Radiol 2010; 14: 037-046DOI: 10.1055/s-0030-1248705ABSTRACTMultiple myeloma is one of the most common hematological malignancies and accounts for significant morbidity and mortality. In the past, detection of myelomatous deposits by radiography was the main method of radiological assessment in this disease. However, in recent years the introduction of whole-body imaging techniques, specifically low-dose whole-body computed tomography, whole-body magnetic resonance imaging, and positron emission tomography, has facilitated a more comprehensive assessment of this heterogeneous and often diffuse disease. Each of these whole-body imaging techniques has specific applications and limitations in the assessment of multiple myeloma that the interpreting radiologist and referring......

The Evolution of Whole-Body Imaging
This article reviews the evolution of whole-body imaging, discussing the history and development of radiography, nuclear medicine, computed tomography (CT), positron emission tomography (PET), combined PET-CT, and magnetic resonance imaging. The obstacles hindering progress toward whole-body imaging using each of these modalities, and the technical advances that were developed to overcome them, are reviewed. The effectiveness and the limitations of whole-body imaging with each of these techniques are also briefly discussed.[...]© Thieme Medical PublishersGet connected:Table of contents | Abstract | Full text (Source: Seminars in Musculoskeletal Radiology)...

Manufacturer says radiation dose from airport scanners minimal
In a recent article entitled Radiation risks: Are airport body scanners ‘a great public health experiment’?”, Leon Kaufman argues that the use of these scanners at airports exposes airline passengers to undetermined amounts of radiation without reason and with little knowledge of the consequences. I would like to address certain incorrect assertions in this article. (Source: Diagnostic Imaging)...

Large fetal size in early pregnancy associated with macrosomia
To assess if fetal size at the time of ultrasound dating examination is associated with the risk of macrosomia and complications associated with macrosomia.This was a retrospective cohort study of 19 377 singleton pregnancies dated in gestational weeks 16-20 during the period 1998-2004 at Danderyd Hospital, Stockholm, Sweden. Obstetric outcome was assessed through linkage to the Swedish Medical Birth Register.When fetuses were [ge] 7 days larger than expected at dating, compared with the expected size according to last menstrual period, there was a 59% increase in the risk of birth weight [ge] 4500 g and a 145% increase in the risk of birth weight [ge] 5000 g (odds ratio (OR), 1.59; 95% CI, 1.12-2.24 and OR, 2.45; 95% CI, 1.22-4.90, respectively). For a birth weight of [ge] 4000 g the risk......
