BACKGROUND: Ultrasonography and magnetic resonance imaging are the most important imaging techniques in the diagnostics of pancreatic carcinoma and disease staging; they are also very useful in monitoring and follow-up of treatment efficacy. The problems with imaging diagnostics arise in certain cases of pancreatic focal lesions - for example in the differentiation of focal chronic pancreatitis and pancreatic carcinoma. Our objectives were the evaluation of ultrasonography and magnetic resonance imaging reliability and determination of the importance of tumor antigen CA 19-9 in the diagnostics of pancreatic carcinoma. METHODS: Our investigation included patients with pancreatic focal mass suspected of malignancy. All patients were examined by ultrasonography, MR, and ultrasound-guided needle biopsy. Cytopathologic examination of biopsied samples was used to diagnose the disease. Oncomarker levels CA 19-9 were assayed in all patients. RESULTS: Magnetic resonance imaging and ultrasonography examination made possible the correct diagnosis of carcinoma in case of 17 patients; in three patients with focal chronic pancreatitis the diagnosis was false positive. No case of false-negative diagnosis was found. The tumor antigen CA 19-9 in serum was determined and it was clearly positive (above 45U/ml) in all patients (17) with pancreatic cancer. CONCLUSION: Imaging techniques gave good results in the evaluation of pancreatic pathology. However, when using imaging techniques differential diagnosis between focal chronic pancreatitis and pancreatic carcinoma seems to be major problem. Correlation of imaging technique and determination of tumor antigen CA 19-9 has an important role in the diagnostics of pancreatic carcinoma. Imaging techniques and identification of tumor antigen CA 19-9 are complementary methods in the examination and diagnostics of pancreatic carcinoma and they allow better precision of diagnosis of pancreatic focal lesions.

Background: Ultrasonography (US) and magnetic resonance (MR) are the most important imaging techniques in the diagnostics of pancreatic carcinoma and disease staging; they are also very useful in monitoring and follow-up of treatment efficacy. The problems with imaging diagnostics arise in certain cases of pancreatic focal lesions - for example in the differentiation of focal chronic pancreatitis and pancreatic carcinoma.

Methods: Our investigation included patients with pancreatic focal mass suspected of malignancy. All patients were examined by ultrasonography, MR, and ultrasound-guided needle biopsy. Cytopathologic examination of the bioptic samples was used to diagnose the disease. Oncomarker CA 19-9 was done in all patients. Results: MR imaging and US examination made possible the correct diagnosis of carcinoma in case of 17 patients; in three patients with focal chronic pancreatitis the diagnosis was false positive. No case of false negative diagnosis was found. The value of oncomarker CA 19-9 was determined and it was clearly positive (over 150 U/ml) in all patients. Conclusion Imaging techniques gave good results in the evaluation of pancreatic pathology. However, when using imaging techniques differential diagnosis between focal chronic pancreatitis and pancreatic carcinoma seems to be major problem. Correlation of imaging technique and identification of CA 19-9 has an important role in the diagnostics of pancreatic carcinoma.

AbstractDue to their important phylogenetic position among extant vertebrates, sharks are an invaluable group in evolutionary developmental biology studies. A thorough understanding of shark anatomy is essential to facilitate these studies and documentation of this iconic taxon. With the increasing availability of cross-sectional imaging techniques, the complicated anatomy of both cartilaginous and soft tissues can be analyzed non-invasively, quickly, and accurately. The aim of this study is to provide a detailed anatomical description of the normal banded houndshark (Triakis scyllium) using computed tomography (CT) and magnetic resonance imaging (MRI) along with cryosection images. Three banded houndsharks were scanned using a 64-detector row spiral CT scanner and a 3 T MRI scanner. All images were digitally stored and assessed using open-source Digital Imaging and Communications in Medicine viewer software in the transverse, sagittal, and dorsal dimensions. The banded houndshark cadavers were then cryosectioned at approximately 1-cm intervals. Corresponding transverse cryosection images were chosen to identify the best anatomical correlations for transverse CT and MRI images. The resulting images provided excellent detail of the major anatomical structures of the banded houndshark. The illustrations in the present study could be considered as a useful reference for interpretation of normal and pathological imaging studies of sharks.
