Investigations Computed tomography (CT) scanning for the detection of hydrocephalus and subarachnoid hemorrhage, grading of hydrocephalus by bicaudate index (Fig. 1), and estimation of Fisher grade (Fisher et al. 1980) on CT scan.
The purpose of the study was to determine the accuracy of the monoclonal antibody (Mab) [Prostascint, Cytogen, Inc.] scan for the detection of nodal metastases using histologic examination of surgical lymphadenectomy specimens as the standard of reference.
The sensitivity and specificity (95% CI) of DECT scanning for the detection of MSU deposition were calculated.
Over the past 20 years, there have been major advances in the field of prenatal screening for Down's syndrome and in the efficacy of ultrasound scanning for the detection of fetal anomalies.
An imaging workshop organized by the Eunice Kennedy Shriver National Institute of Child Health and Human Development in the United States reached a consensus that all pregnant women should be offered an ultrasound scan for the detection of fetal anomalies and pregnancy complications [ 20].
In our practice, we have found PET-CT to be more sensitive than 99mTc bone scan for the detection of osseous metastases in several children with RMS or EWS (Fig. 4).
Diagnostic assessment of small pulmonary nodules requires serial CT scanning for the detection of morphological changes, and the availability of reliable software for fully automated three-dimensional segmentation and highly consistent volume measurement of lung nodules has become essential in evaluating growth as evidence of potential malignancy (Wiemker et al, 2005; Marchianò et al, 2009).
Our search attempted to capture all the studies that reported the diagnostic accuracy of sentinel node biopsy, positron emission tomography (PET), magnetic resonance imaging (MRI), computer tomography (CT) and ultrasound scanning for the detection of lymphatic spread in primary endometrial cancer.
A prospective study recommended one systematic F-FDG PET/CT at 3 6 months after treatment as the optimal timing (Krabbe et al, 2009), which was confirmed by our data showing the sensitivity of a 3 6-month F-FDG PET/CT scan for the detection of early recurrence.
