Occupational Diseases: Asbestosis and Mesothelioma in Forensic Practice
2019
Diagnosis of occupational diseases, a strong collaboration between radiologic and clinical features with related occupational history and literature supporting, and an association between the exposure and the disease process are requested. Further pathological findings emerging at biopsy or autopsy, which are considered ancillary examination techniques, may assist in the judgment related to causal chain reconstruction.
Case Report: Unusual Clinical Presentation of a Rare Cardiac Inflammatory Myofibroblastic Tumor in Children: The Differential Diagnosis With Pediatri…
2021
Introduction: There are still no guidelines about pediatric cardiac cancers. The purpose of this work is to provide new scientific data facilitating the differential diagnosis of a rare cardiac tumor with an unusual presentation, such as the cardiac inflammatory myofibroblastic tumor (IMT).Case Presentation: A 3-year-old male child presented with several symptoms including unconsciousness, vomiting, and drowsiness. A clinical and neurological examination revealed a unilateral (right) motor delay and positive unilateral Babinski sign. Electrocardiogram (ECG) was normal.Diagnostic Assessment: The total body computed tomography (CT) scans showed hypodensity in the left temporal–parietal lobe, …
Die Aktivität der Rückenstreckmuskulatur beim aufrechten Stehen und beim Sitzen mit standidentischer Rumpfhaltung - eine elektromyographische Studie
2001
Problem: There is a controversial discussion about the loading of the spine by the force of the extending muscles of the back in upright sitting with the back curved as in upright standing. Experimental studies investigating this issue are still lacking. Methods: In the study presented in this paper we measured in 30 subjects the activity of the extending back muscles both in a natural upright standing posture and in sitting with identical posture of the back as recommended in some back training programs. To this end we recorded the electromyographical surface activity of the back muscles at four levels of the spine in both postures. The EMG activities were intraindividually normalized with…
Three-dimensional transesophageal echocardiography in the guide of cardiac mass biopsy
2017
Cardiac tumors are rare. Cardiovascular imaging is more important in the differential diagnosis of cardiac masses but no current noninvasive diagnostic tool has the ability to absolutely diagnose cardiac tumors. In effect cardiac biopsy remains the gold standard in the differential diagnosis. In our case we show the advantages of three-dimensional (3D) transesophageal echocardiography as a guide for cardiac biopsy. We believe that 3D TEE is ready to be used in the guide of cardiac mass biopsy. Once interventionalists become confident with 3D imaging, this technique should be used routinely during these procedures.
Correlation between rCBF, Angiography, EEG and Scanning in Brain Tumors
1969
The findings with techniques of different sensitivity, and which investigate different aspects of brain structure and/or function are difficult to correlate. However, such a comparison should help in elucidating the physiopathological mechanisms of brain lesions and the postoperative clinical evolution and prognosis in cases of brain tumors.
Zonal Segmentation of Prostate T2W-MRI using Atrous Convolutional Neural Network
2019
The number of prostate cancer cases is steadily increasing especially with rising number of ageing population. It is reported that 5-year relative survival rate for man with stage 1 prostate cancer is almost 99% hence, early detection will significantly improve treatment planning and increase survival rate. Magnetic resonance imaging (MRI) technique is a common imaging modality for diagnosis of prostate cancer. MRI provide good visualization of soft tissue and enable better lesion detection and staging of prostate cancer. The main challenge of prostate whole gland segmentation is due to blurry boundary of central gland (CG) and peripheral zone (PZ) which lead to differential diagnosis. Sinc…
Magnetresonanztomographie in der Diagnostik des Kollumkarzinoms. Computertomographische und histologische Korrelation
1988
The value of magnetic resonance tomography in the diagnosis of carcinoma of the cervix was studied in a prospective series of 20 patients. The results were compared with those of computed tomography and with the clinical findings. The diagnosis depended on the postoperative histology. Gynaecological examination proved superior to imaging methods in determining the extent of local tumour spread. Tumour involvement of the regional lymphatic system was better demonstrated by MRT than by CT. Exact staging proved inadequate with both these methods and the new imaging methods have not produced any changes in operative planning or technique.
Softwareassistierte CT-Nachverarbeitung am Beispiel der Karotiden
2004
Ziel der Arbeit: Es sollte ein Softwareassistent fur die automatisierte Auswertung von CT-Angiographien entwickelt werden, der die Visualisierung des Gefaslumens und eine quantitative Auswertung von Stenosen ermoglicht. Die klinische Erprobung erfolgt am Beispiel der A. carotis. Methodik: Bei insgesamt zwolf Patienten mit Verdacht auf eine hohergradige Stenose der Karotiden wurde eine CT-Angiographie (CTA) mit einem Mehrzeilen-CT durchgefuhrt. Diese Daten wurden mit dem neuen Softwareassistenten analysiert und ausgewertet. Die Ergebnisse verglich man mit der digitalen Subtraktionsangiographie (DSA). Ergebnisse: Die Nachverarbeitungszeit der CT-Datensatze mit Hilfe des Softwareassistenten li…
Mechanical recanalization in basilar artery occlusion: The ENDOSTROKE study
2015
Objective A study was undertaken to evaluate clinical and procedural factors associated with outcome and recanalization in endovascular stroke treatment (EVT) of basilar artery (BA) occlusion. Methods ENDOSTROKE is an investigator-initiated multicenter registry for patients undergoing EVT. This analysis includes 148 consecutive patients with BA occlusion, with 59% having received intravenous thrombolysis prior to EVT. Recanalization (defined as Thrombolysis in Cerebral Infarction [TICI] score 2b–3) and collateral status (using the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology collateral grading system) were assessed by a blinded core l…
