K Šimeček, P Látal, J Duda, M Šimeček
PURPOSE OF THE STUDY Our retrospective study presents the comparison of the preoperative magnetic resonance imaging of the knee joint - MRI - and the arthroscopic finding - ASC. Its aim is to find out how a positive or a negative finding of MRI corresponds with the operative finding and how much the experience of radiologist contributes to the conformity. MATERIAL AND METHODS The MRI findings of knee joints treated surgically at two departments in 2013 and 2014 were assessed. The MRI was performed in a total of 470 patients who subsequently underwent an arthroscopic surgery...

Uterine anatomy and uterine fibroids (UFs) characteristics have been classically considered as almost a unique issue in gynecology and reproductive medicine. Nowadays, the management of UF pathology is undergoing an important evolution, with the patient's quality of life being the most important aspect to consider. Accordingly, surgical techniques and aggressive treatments are reserved for only those cases with heavy symptomatology, while the clinical diagnostic based on size and number of UFs remains in a second plane in these situations...

BACKGROUND: This review focuses on the initial presentation of women who suspect that they are infertile, and how best to assess the anatomy of their uterus and ovaries in order to investigate the cause of their infertility, and potentially improve desired fertility outcomes. This review was undertaken as part of a World Health Organization initiative to assess the evidence available to address guidance for the diagnosis and treatment of infertility within a global context. Providing access to care for infertile women will help to ease the psycho-social burdens, such as ostracization, intimate partner violence and other negative consequences of being involuntarily childless or unable to become pregnant despite desiring a biological child or children...

Rebecca Peebles, Christopher E Jonas
Sacroiliac joint (SIJ) dysfunction is a common cause of low back pain in the athlete, especially in sports with repetitive, asymmetric loading. Complex anatomy and broad pain referral pattern make diagnosis difficult. Identifying three or more positive physical examination maneuvers for the SIJ improves examination sensitivity and specificity. Imaging is rarely helpful in establishing the diagnosis but is often used to rule out other pathology. Conservative management with activity modification, medication, physical therapy, manipulation and bracing is first line treatment...

Biological motion is a problem for non- or mini-invasive interventions when conducted in mobile/deformable organs due to the targeted pathology moving/deforming with the organ. This may lead to high miss rates and/or incomplete treatment of the pathology. Therefore, real-time tracking of the target anatomy during the intervention would be beneficial for such applications. Since the aforementioned interventions are often conducted under B-mode ultrasound (US) guidance, target tracking can be achieved via image registration, by comparing the acquired US images to a separate image established as positional reference...

INTRODUCTION: The nails have a functional and esthetic importance for patients. Almost always, the nail disorders are diagnosed on the basis of clinical findings, but imaging methods may be required for a better assessment. These imaging methods, such as ultrasound and magnetic resonance, may help to establish an accurate diagnosis. Magnetic resonance imaging is not widely available and sometimes may be very expensive; that is why, ultrasound is an excellent imaging modality. Our objective is to expose the nail unit anatomy, the nail unit anatomy in ultrasound, and some of the frequent pathologies found in our daily practice...

Glioblastoma (GBM) is the most aggressive malignant brain cancer in adults, and its poor prognosis and resistance to the existing standard of care require the development of innovative therapeutic modalities. The local delivery of stem cells as therapeutic carriers against glioma has produced encouraging results, but encounters obstacles with regards to the repeatability and invasiveness of administration. Intranasal delivery of therapeutic stem cells could overcome these obstacles, among others, as a noninvasive and easily repeatable mode of administration...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

Sacral-iliac fixation techniques may be indicated in the management of various lumbosacral pathologies including spinal degeneration, infection, tumour resection, fracture, pseudarthrosis, correction of spinal deformities involving long fusion constructs to the sacrum and cases with poor sacral fixation. There are a number of options for lumbosacral fixation each with their own advantages and disadvantages. Though S2-alar-iliac (S2AI) have demonstrated promising advantages over alternatives, the complex anatomy of the spinopelvic region demands precise insertion of the screws to create a biomechanically robust construct safely...

BACKGROUND: TEVAR has dramatically expanded treatment options for patients with thoracic aortic pathology. The interaction between endografts and the dynamic anatomy of the thoracic aorta is not well characterized for repetitive physiologic stressors and subsequent issues related to long-term durability. Through 3D modeling we sought to quantify cardiac-induced aortic deformation before and after TEVAR to assess the impact of endografts on dynamic aortic anatomy. METHODS: Eight patients with acute (n = 4) or chronic (n = 3) Type B dissections, or chronic arch aneurysm (n = 1), underwent TEVAR with a single (n = 5) or multiple (n = 3) Gore C-TAG(s)...

Diagnosis of corneal disease and challenges in corneal transplantation require comprehensive understanding of corneal anatomy, particularly that of the posterior cornea. Micro-optical coherence tomography (µOCT) is a potentially suitable tool to meet this need, owing to its ultrahigh isotropic spatial resolution, high image acquisition rate and depth priority scanning mode. In this study, we explored the ability of µOCT to visualize micro-anatomical structures of the posterior cornea ex vivo and in vivo using small and large animals...

Neurosurgeons are getting increasingly involved in surgery for orbital tumours. The various approaches to the orbit can be challenging. The authors have demonstrated on cadavers the various approaches to the orbit which are required to be mastered by the neurosurgeon. The superior approaches which include the transcranial, supraorbital and the hybrid approaches are the most commonly utilized surgical approaches by the neurosurgeon for excision of orbital pathologies. The lateral orbitotomy is an elegant approach for excision of the tumours lateral to the optic Nerve and lacrimal gland tumours...
