Introduction. Low back pain (LBP) is common in children and adolescents. There are many factors that cause LBP, including\nstructural disorders, degenerative changes, Scheuermann�s disease, fractures, inflammation, and tumors. Magnetic Resonance\nImaging is the gold standard for diagnosing spinal abnormalities and is mandatory when neurological symptoms exist. The study\nfocuses on common MRI findings in adolescents with persistent LBP, without history of acute trauma or evidence of either\ninflammatory or rheumatic disease.Materials and Methods. Eleven adolescentswere submitted to thoracic and/or lumbar spineMRI\ndue to persistent LBP.The protocol consisted of T1WI, T2WI, and T2WI with FS, in the axial, sagittal, and coronal plane. Results.\nMRI revealed structural abnormalities (scoliosis and kyphosis) in 4/11 (36.36%); disc abnormalities and endplate changes were\nfound on 11/11 (100%). Typical Scheuermann�s disease was found in 3/11 (27.27%). Endplate changes were severe in Scheuermann�s\npatients and mild to moderate in the remaining 8/11 (72.72%). Kyphosis was in all cases secondary to Scheuermann�s disease. Disk\nbulges and herniaswere found in 8/11 (72.72%), all located in the lumbar spine. Conclusion. In adolescents with LBP, structural spinal\ndisorders, degenerative changes, and Scheuermann�s disease are commonly found on MRI; however, degenerative changes prevail....
Purpose. Intracranial hypotension (IH) often remains undetected using current MR diagnostic criteria. This project aims to\ndemonstrate that central incisural herniation is highly effective in helping to make this diagnosis. Materials and Methods.Magnetic\nresonance imaging (MRI) was analyzed in 200 normal and 81 clinically known IH patients. MRI reference lines approximating the\nplane of the incisura, the plane of the diaphragma sella, the plane of the foramen magnum, and the plane of the visual pathway\nwere utilized to measure the position of selected brain structures relative to these reference lines. Results. All IH patients had highly\nstatistically significant (...
Metastases to the breast from non-mammary primary tumors are uncommon. We present a rare, but typical, case\nof metastasis to the breast from lung carcinoid tumor, 20 years after the primary cancer was treated....
Aim. The aim of the study was to determine the most commonly diagnosed neoplasms in the MRI scanned patient population\nand indicate correlations based on the descriptive variables. Methods. The SPSS software was used to determine the incidence of\nneoplasms within the specific diagnoses based on the descriptive variables of the studied population. Over a five year period, 791\npatients and 839 MRI scans were identified in neoplasm category (C00-D48 according to the International Statistical Classification\nof Diseases and Related Health Problems ICD-10). Results. More women (56%) than men (44%) represented C00-D48. Three\ncategories of neoplasms were recorded. Furthermore, benign neoplasms were the most numerous, diagnosed mainly in patients\nin the fifth decade of life, and included benign neoplasms of the brain and other parts of the central nervous system. Conclusions.\nMales � 30 years of age with neoplasms had three times higher MRI scans rate than females of the same age group; even though\nfemales had much higher scans rate in every other category. The young males are more often selected for these scans if a neoplasm\nis suspected. Finally, the number of MRI-diagnosed neoplasms showed a linear annual increase....
Objectives. Diagnostic guidelines for chronic obstructive pulmonary disease (COPD) are based on spirometry and clinical criteria.\nHowever, this does not address the pathophysiological complexity of the disease sufficiently. Until now, inspiratory chest\ncomputed tomography (CT) has been considered as the preferred imaging method in these patients. We hypothesized that\nexpiratory CTmay be superior to demonstrate pathophysiological changes. The aim of this prospective study was to systematically\ncompare lung function tests with quantified CT parameters in inspiration and expiration. Materials and Methods. Forty-six\npatients with diagnosed COPD underwent spirometry, body plethysmography, and dose-optimized CT in maximal inspiration\nand expiration. Four quantified CT parameters were acquired in inspiration, expiration, and their calculated delta values. These\nparameters were correlated with seven established lung function parameters. Results. For inspiratory scans, a weak-to-moderate\ncorrelation with the lung function parameters was found. These correlations significantly improved when adding the expiratory\nscan (p<0.05). Moreover, some parameters showed a significant correlation only in expiratory datasets. Calculated delta values\nshowed even stronger correlation with lung function testing. Conclusions. Expiratory quantified CT and calculated delta values\nsignificantly improve the correlation with lung function parameters. Thus, an additional expiratory CTmay improve image-based\nphenotyping of patients with COPD....
