A fully automatic 2D segmentation method for uterine fibroid in MRgFUS treatment evaluation

2015

PurposeMagnetic Resonance guided Focused UltraSound (MRgFUS) represents a non-invasive surgical approach that uses thermal ablation to treat uterine fibroids. After the MRgFUS treatment, an operator must manually segment the treated fibroid areas to evaluate the NonPerfused Volume (NPV). This manual approach is operator-dependent, introducing issues of result reproducibility, which could lead to errors in the subsequent follow-up phase. Moreover, manual segmentation is time-consuming, and can have a negative impact on the optimization of both machine-time and operator-time. MethodTo address these issues, in this paper a novel fully automatic method based on the unsupervised Fuzzy C-Means cl…

Anterior Cervical Subaxial Treatment (Fusion)

2019

Cervical radiculopathy caused by a soft disc herniation or a foraminal stenosis is a common problem. While symptoms from soft disc herniations have high chances to recover after conservative therapy persisting radicular pain or a neurological deficit are accepted as an indication for surgical treatment. The surgical technique regarded as gold standard for cervical radiculopathy due to a disc herniation or foraminal stenosis is an anterior cervical discectomy followed by fusion. The chapter will outline the indications for anterior cervical discectomy, the clinical and radiographic results as well as the potential complications and secondary problems.

Tube Housing Leakiness Radiation and Patient Related Radiation Protective Measures – Gonads Radiation Exposure from Panoramic Radiography

2009

The purpose of this study was to compare patient- and apparatus related radiation protective measures considering gonad radiation exposure at panoramic radiography. The local dose (yGv) in the region of the gonads of a male Alderson-Rando-Phantom was measured by the dosimeter Tol-F (Berthold Technology, Germany) during panoramic radiography (PR) by the digital Orthophos XG plus®(Sirona / Bensheim, Germany). Different radiation protective measures was investigated during constant exposure parameters. In the second part of the survey the same ionisation chamber recorded the scattered radiation at the gonads level of the none protected phantom at various case shielding. Without protection apro…

Aussagefähigkeit und Stellenwert von bildgebender Diagnostik und Duplexsonographie bei Neugeborenen mit nekrotisierender Enterokolitis

1994

In this prospective study 101 sonographic examinations of superior mesenteric artery blood flow velocities, indices and blood flow volume were consecutively performed in 41 newborn to diagnose necrotising enterocolitis (NEC). Intramural and portal venous gas was also estimated. The artifacts of air in the AMS and the portal system were examined in an experimental study. The results of sonography and abdominal radiography were equivalent in the case of definitely established NEC, portal venous gas being more sensitive to detection by sonography. Abdominal radiography was indicated as the primary examination in case of a clearly identified clinical course. Sonography should be performed so th…

Diagnosis and Planning in Immediate Loading: Surgical Diagnosis

2019

For several decades, two-dimensional images were the only available for the surgical diagnosis prior to implant placement. The introduction of digital radiology and software applications for three-dimensional imaging has increased the prospects of success in implant diagnosis and surgical placement. The CBCT is definitely more precise and complete than panoramic radiography, but it is not always mandatory for every case. Success for fixed implant-supported rehabilitations, especially in immediate provisionalization techniques, depends on accurate pre-surgical evaluation of the following issues: (1) recognize feasible restoration procedures to rehabilitate patient edentulism; (2) list all th…

Imaging Assessment of Gastroduodenal Perforations.

2016

Gastroduodenal perforation is an emergency situation that usually requires early recognition and well-timed surgical treatment. It can arise from different natural, iatrogenic, or traumatic causes, and it can present with various symptoms especially in the early phase. This article reviews the role of the different imaging techniques in the diagnosis of gastroduodenal perforation, focusing on the direct and indirect signs that are encountered in conventional radiography and computed tomography; our personal experience is also provided.

The assessment of vertebral fractures in elderly women with recent hip fractures: the BREAK Study

2012

This study aimed to evaluate the prevalence of vertebral fractures in elderly women with a recent hip fracture. The burden of vertebral fractures expressed by the Spinal Deformity Index (SDI) is more strictly associated with the trochanteric than the cervical localization of hip fracture and may influence short-term functional outcomes. INTRODUCTION: This study aimed to determine the prevalence and severity of vertebral fractures in elderly women with recent hip fracture and to assess whether the burden of vertebral fractures may be differently associated with trochanteric hip fractures with respect to cervical hip fractures. METHODS: We studied 689 Italian women aged 60 years or over with …

Burned to the Bone

2017

A burn-related injury that had worsened over time was compatible upon radioclinical examination with severe psoriatic arthritis (PsA), but was missing several essential characteristics of that disorder. A 58-year-old woman with no personal or family history of rheumatic diseases consulted for hand arthralgia. Her medical history was marked by severe burns to 80% of her body, sparing the face and the back, following a gas explosion 20 years earlier. …
