Abstract

Magnetic resonance imaging (MRI) of the scrotum represents a useful supplemental imaging technique in the characterization of scrotal masses, particularly recommended in cases of nondiagnostic ultrasonographic findings. An accurate characterization of the benign nature of scrotal masses, including both intratesticular and paratesticular ones may improve patient management and decrease the number of unnecessary radical surgical procedures. Alternative treatment strategies, including follow-up, lesion biopsy, tumor enucleation, or organ sparing surgery may be recommended. The aim of this pictorial review is to present how MRI helps in the characterization of sonographically indeterminate scrotal masses and to emphasize the key MRI features of benign scrotal masses.

Abstract

PURPOSE To investigate in otherwise healthy children the association between the caries index, the stimulated salivary flow rate (SFR), and the spectral Doppler findings of the changes in blood perfusion in the salivary glands during the secretion of saliva. MATERIALS AND METHODS The study group consisted of 38 children with a mean age of 9.47 ± 1.89 years. The caries index was calculated by determining the number of decayed, missing, and filled teeth. Groups A, B, and C represented subjects with low, moderate, and normal SFRs, respectively, calculated by obtaining chewing-stimulated whole saliva. All subjects were examined by color Doppler ultrasonography (CDUS) before and during secretory stimulation with lemon, by which maximum systolic velocity (MSV), pulsatility index (PI), resistive index (RI), and flow volume (FV) were calculated at the external carotid and facial arteries. RESULTS The differences for spectral indices obtained before and after stimulation were significantly different among Groups A, B, and C at the external carotid artery (P = 0.006 for delta MSV, P = 0.014 for delta PI, P < 0.001 for delta RI, and P = 0.022 for delta FV) and at the facial artery (P = 0.001 for delta MSV, P = 0.004 for delta PI, P < 0.001 for delta RI, and P < 0.001 for delta FV). In addition, significant correlations were calculated between the SFR and the aforementioned delta values. CONCLUSION CDUS enabled the evaluation of changes in blood perfusion in the salivary glands during salivary stimulation and may be a promising tool for the assessment of caries risk in children.
