Acute and overuse elbow trauma: radio-orthopaedics overview.

The correct management of acute, subacute and overuse-related elbow pathologies represents a challenging diagnostic and therapeutic problem. While major trauma frequently requires a rapid surgical intervention, subluxation and minor trauma allow taking more time for diagnostics and planning the correct elective treatment after careful clinical and radiological investigation. In these conditions, communication between orthopaedic surgeon and radiologist allow to create a detailed radiology report, tailored to the patient's and surgeon's needs and optimal to plan proper management.

Imaging of articular cartilage: current concepts.

Magnetic resonance imaging (MRI) is the gold standard method for non-invasive assessment of joint cartilage, providing information on the structure, morphology and molecular composition of this tissue. There are certain minimum requirements for a MRI study of cartilage tissue: machines with a high magnetic field (> 1.5 Tesla); the use of surface coils; and the use of T2-weighted, proton density-weighted fast-spin echo (T2 FSE-DP) and 3D fat-suppressed T1-weighted gradient echo (3D-FS T1W GRE) sequences.

[Ultrasound-guided biopsy of the testis: indications and results].

Ultrasound examination of the testis is the imaging modality of choice for the evaluation of intratesticular focal lesions. In spite of its high sensibility, eco-Doppler-elastography is lacking of specificity in discrimination between benign and malign lesions, not always allowing us to make a definitive diagnosis of malignancy. When a diagnostic doubt persists, for such lesions that are indeterminate at clinical and radiological evaluation, it is possible to recur to ultrasound-guided testicular needle biopsy.

[Role of urographic 64 CT examination for the evaluation of kidney inflammation diseases].

In the study of inflammatory kidney diseases, the use of integrated imaging is considered the best diagnostic approach. However, given the high cost of radiological examinations, the radiologist is responsible for the choice of the best method to solve the question asked by the clinician. In this paper are presented the main imaging methods for the study of pyelonephritis and, based on our experience, it is emphasized the role of multidetector Computed Tomography urographic technique in the identification, characterization and subsequent follow-up of inflammatory kidney diseases.

[Choice of the imaging technique for the diagnosis of bone metastases].

Bone is the third common site of distant metastases in cancer patients. Bone metastases may have implications for prognosis, quality of life, and local and systemic therapy. Numerous imaging modalities may be used to detect bone metastases.

[Cardiac sympathetic innervation imaging with myocardial MIBG scintigraphy].

Metaiodobenzylguanidine (MIBG) was developed initially as a tracer for oncological imaging; when labeled with 123 I or 131 I, it may detect APUDomas, such as pheochromocytomas and paragangliomas. In the last years, MIBG has found an important role also in neurology and cardiology, as cardiac innervation tracer. Actually, MIBG cardiac imaging is a universally accepted method to estimate cardiac sympathetic innervations.

[Effectiveness of conventional diagnostic radiology and nuclear medicine in the treatment of pain from bone metastases].

Bone is one of the most common metastasis sites from solid tumors. Bone pain due to metastatic neoplastic growth is due to tumor infiltration and expansion of bone membranes. Treatment of acute and chronic pain represents one of the greatest problems in clinical oncology, requiring a multidisciplinary approach.
