RTE demonstrated all testicular tumors as lesions with increased tissue stiffness. Because of its higher specificity, RTE can provide additional information in cases with indeterminate US findings.

ObjectiveOwing to the widespread use of abdominal imaging studies the detection rate of solid renal masses has increased, and an accurate characterisation of imaging features of renal masses has become more essential for case management.Method and resultsMR imaging (MRI) and computed tomography (CT) are frequently used modalities for detection and differentiation of renal masses. This article gives a review of imaging characteristics of benign and malignant renal masses, discussing their appearance in CT and MR imaging. Advanced MR techniques like diffusion-weighted imaging and apparent diffusion coefficient (ADC) mapping, which have shown promising results in the differentiation between benign and malignant renal lesions, will be introduced.ConclusionMRI and CT are useful in the characterisation and estimation of the prognosis for renal masses.

Ultrasonography is the standard modality to image the scrotum because it can provide information about volume, echo texture, tissue stiffness and functional information that includes macrovascularization and microvascularization. Indeed, ultrasound imaging is indicated in the presentation of acute scrotal pain and swelling to differentiate between testicular torsion, infarction and inflammation, as well as being the modality of choice when an intrascrotal mass is suspected. Advances in ultrasonography technology have produced new innovative techniques for imaging the scrotum, including grey-scale ultrasound, Doppler ultrasonography, contrast-enhanced ultrasonography and real-time sonoelastography. Each of these techniques provides information that can be useful when diagnosing diseases and disorders of the testicles. Consequently, the standard approach to accurate diagnosis should rely on multiparametric ultrasonography techniques, rather than just one or two techniques in isolation.

Objectives. To evaluate prostate cancer (PCa) detection rates of real-time elastography (RTE) in dependence of tumor size, tumor volume, localization and histological type. Materials and Methods. Thirdy-nine patients with biopsy proven PCa underwent RTE before radical prostatectomy (RPE) to assess prostate tissue elasticity, and hard lesions were considered suspicious for PCa. After RPE, the prostates were prepared as whole-mount step sections and were compared with imaging findings for analyzing PCa detection rates. Results. RTE detected 6/62 cancer lesions with a maximum diameter of 0–5 mm (9.7%), 10/37 with a maximum diameter of 6–10 mm (27%), 24/34 with a maximum diameter of 11–20 20 mm (70.6%), 14/14 with a maximum diameter of >20 mm (100%) and 40/48 with a volume ≥0.2 cm3 (83.3%). Regarding cancer lesions with a volume ≥ 0.2 cm³ there was a significant difference in PCa detection rates between Gleason scores with predominant Gleason pattern 3 compared to those with predominant Gleason pattern 4 or 5 (75% versus 100%; P = 0.028). Conclusions. RTE is able to detect PCa of significant tumor volume and of predominant Gleason pattern 4 or 5 with high confidence, but is of limited value in the detection of small cancer lesions.

SummaryBackgroundThe assessment of hiatal hernias (HH) is typically done with barium swallow X‑ray, upper endoscopy, and by high-resolution esophageal manometry (HRM). The aim of this study was to assess the clinical utility of these methods in terms of HH detection and their correlation to gastroesophageal reflux disease (GERD).MethodsA retrospective comparative analysis of patients with symptoms of GERD was carried out. The performance of endoscopy and HRM in diagnosing HH was assessed, taking barium swallow X‑ray as a reference. Furthermore, statistically comparative analysis between detected hernias and the presence of reflux disease in ambulatory impedance-pH monitoring (MII) was performed.ResultsOverall, 112 patients were analyzed. Barium swallow X‑ray showed no correlation either to HR manometrically or to endoscopically assessed HH. Significant accordance in the detection rate of HH was proved between HRM and gastroesophagoscopy (p < 0.001). Only endoscopically assessed HH showed a significant correlation with GERD (p = 0.047). No correlation between detected hernias and GERD could be found either with HRM or with barium swallow X‑ray.ConclusionsBarium swallow X‑ray provided the highest rate of HH detection (76.8%). For the reliable exclusion of HH prior to treatment, all three mentioned investigations appear to be necessary in order of low conformity.
