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.

Magnetic resonance imaging (MRI), a useful technique of studying soft tissues of the body, can be very effective in assessing the integrity of tendons. Usually a patient with a complete tear of the posterior tibial tendon has characteristic physical findings. In the patient presented, MRI demonstrated a complete disruption of the posterior tibial tendon, despite the absence of the commonly associated clinical findings. In view of the difficulties encountered with attempted tenography of the completely torn posterior tibial tendon, MRI provides a sensitive alternative diagnostic technique.

Background and objective: Musculoskeletal injuries frequently occur in the ankle in both the athletic and general population. Ankle sprains are among the most frequent types of ankle injuries, which are conventionally diagnosed through clinical examinations. However, magnetic resonance imaging can provide a more precise diagnosis, leading to better injury management and prevention of consequent chronic complications. The present study aimed to examine the significance of magnetic resonance imaging in detecting and assessing changes that occur in ligaments and soft tissues in patients with ankle sprains. Methods: In a prospective study, 50 patients with ankle sprain referred to Rizgary and Erbil Teaching hospitals in Erbil city, Iraqi Kurdistan Region, from March 2018 to April 2019, were included in the study. They underwent clinical evaluation and MRI (GE general electric 1.5 Tesla). Two expert radiologists analyzed the magnetic resonance imaging images, and the results were compared. The collected data were analyzed using SPSS version 23 through descriptive statistics. Results: Most patients (64%) belonged to the age groups of 30-49 years old. Most of them (64%) were males. Most events of ankle sprain (66%) were because of sports and accidents. The clinical evaluation proved 82% of the ankle sprains. Regarding the laterality of the lesions, 60% were spotted in the right ankles and 40% in the left. According to magnetic resonance imaging results, both radiologists diagnosed that the ankle sprains included bone lesions, ligament injury, tendon injury, and effusion. There was an agreement of ≥ 96% between the two radiologists in this regard. The two radiologists were not significantly different in terms of diagnosing the ligament side. As reported by the radiologists based on the magnetic resonance imaging images, the anterior, lateral, and medial tendons were normal in most cases. Conclusion: Magnetic resonance imaging is a vitally important tool that can be utilized reliably and accurately to diagnose and evaluate changes in ligaments and soft tissues in patients with ankle sprains.

Difficulties in diagnosis and therapy of scleroderma-panniculitis (S-PN), one of the variants of the septal PN, are discussed. Feasibility of ultrasonography, magnetic resonance imaging of soft tissues and histological examination of the lesions in order to set the diagnosis of PN in time is considered. The clinical case of S-PN combined with antiphospholipid syndrome is presented.

An experimental series in the rabbit was performed to test gadolinium-DTPA (Gd-DTPA) enhancement of VX-2 carcinoma and hemorrhages induced in the soft tissues. The recognition of both malignant and benign lesions was greatly facilitated on T1 weighted images after intravenous administration of 0.3 mmol Gd-DTPA/kg body weight because of reduced T1 relaxation times. Gd-DTPA enhancement reached its maximum after 10–15 minutes and was most apparent in tumor tissue, connective tissue surrounding the tumor and in the area of fresh hemorrhage.

Abstract Magnetic resonance imaging (MRI) is a promising diagnostic method for evaluation of bone marrow myelofibrosis for offering non-invasive, wider-area coverage over conventional histology. Although the most striking feature in histology of myelofibrotic bone marrow is the proliferation of reticulin fibers, the spectrum of findings involves abnormalities in cell number and composition, vessel proliferation, as well as possible pre-fibrotic abnormalities in matrix such as inflammation/edema. Correlation of MRI observations with such histological findings to accurately define the pathogenic phases of myelofibrosis has been challenging. Here, we present the first MRI analysis of myelofibrosis in a mouse model (Gata-1low mice) in an attempt to correlate MRI signal observations with histological findings. T2-weighted MRI images of femur bone marrow of Gata-1low animals at different ages (12 to 46 weeks) showed high MR signal intensity, absent in age-matched wild-type controls, that is detected as early as 12 weeks of age, before onset of histologically-defined fibrosis in this mouse model. MRI acquisitions employing fat suppression, a technique that suppresses signals from lipids, together with the absence of chemical shift artifacts in the images, excluded the possibility of lipids as the source of the prominent MR signal. To determine the source of this prominent non-lipid signal in Gata-1low bone marrow, cellular composition, vascularization and vascular permeability were tested. Our findings demonstrate a multi-source nature of MRI signals in bone marrow, which evolves from young (12 weeks) to old (40 weeks) Gata-1low bone marrow consistent with the pathologic progression of myelofibrosis. Data support the importance of an integrative approach to further the development of this non-invasive modality for following the dynamics and progression of this multifactorial pathology in humans.
