Thirty Minutes of Running Exercise Decreases T2 Signal Intensity but Not Thickness of the Knee Joint Cartilage: A 3.0-T Magnetic Resonance Imaging Study.

Objective: Recent studies showed a potential of magnetic resonance imaging (MRI), which can be used as an additional tool for diagnosing cartilage degeneration in the early stage. We designed a cross-sectional study in order to evaluate knee joint cartilage adaptation to running, using 3.0-T MRI equipped with the 3-dimensional turbo spin echo (VISTA = Volume ISotropic Turbo spin echo Acquisition) software.

Determination of the width of the presacral space on magnetic resonance imaging.

Presacral space enlargement may be the first sign of certain diseases. The normal width of the presacral space has not been widely investigated and in all previous studies was calculated from lateral radiographs obtained at barium enema examination. Our study determined the normal width of the presacral space on MRI and investigated a possible difference between men and women.

A 34-week-old male fetus with short rib polydactyly syndrome (SRPS) type I (Saldino-Noonan) with pancreatic cysts.

A 34-week-old male fetus (first diagnosed at 28 weeks of gestation) with short rib polydactyly type I Saldino-Noonan syndrome is presented in this study. In the postmortem examination of the fetus, pancreatic dysplasia, multiple cysts and multicystic dysplastic kidneys, omphalomesenteric cyst, ascites, malrotation, micropenis, undescended testes, bilateral inguinal hernia and hydrops were observed. The parents were first-degree cousins.
