2. Editorial Comment: Robotic versus other nephroureterectomy techniques: a systematic review and meta-analysis of over 87,000 cases
ABSTRACT Purpose Preoperative computed tomography or magnetic resonance (MR) imaging are commonly used for radiological evaluation of renal cell carcinoma (RCC) before radical nephrectomy or nephron sparing surgery(NSS). This study aimed to assess the role of MRI for predicting postoperative renal function by preoperative estimation of renal parenchymal vo

6. 7.0T ultrahigh-field MRI directly visualized the pedunculopontine nucleus in Parkinson’s disease patients
OBJECTIVES: The pedunculopontine nucleus (PPN) is considered a promising new target for neurostimulation in Parkinson’s disease (PD) patients with postural instability and gait disturbance that is refractory to other treatment modalities. However, the PPN is typically difficult to visualize with magnetic resonance imaging (MRI) at clinical field strengths

8. Prostate cancer recurrence in vas deferens – fusion image guide as an important tool in dignosis
ABSTRACT The biochemical recurrence after local treatment for prostate cancer is an often challenging condition of clinical management. The aim of this report is to demonstrate the importance of the association of various imaging methods in the identification and subsequent accurate percutaneous biopsy in patients with recurrence of prostate cancer, especial

9. Pattern recognition of abscesses and brain tumors through MR spectroscopy: Comparison of experimental conditions and radiological findings
Abstract Introduction The interpretation of brain tumors and abscesses MR spectra is complex and subjective. In clinical practice, different experimental conditions such as field strength or echo time (TE) reveal different metabolite information. Our study aims to show in which scenarios magnetic resonance spectroscopy can differentiate among brain tumors,

10. The value of magnetic resonance imaging in the diagnosis of penile fracture
Purpose We studied the use of magnetic resonance imaging in the diagnosis of penile fracture. Materials and Methods Between 1997 and 2012, fifteen patients (age range 17-48 years, mean age 37 years) with suspected penile fracture underwent MRI examinations. Ten patients were injured during sexual intercourse, whereas four patients were traumatized by non-ph

11. Assessing joint effusion and bone changes of the head of the mandible in MR images of symptomatic patients
The aim of the present study was to investigate the relationship between degenerative bone changes of the head of the mandible and the presence of joint effusion (JE). This study was based on sagittal magnetic resonance imaging (MRI) reports of 148 temporomandibular joints (TMJs) of 74 patients complaining of pain and/or dysfunction in the TMJ area. The mand

12. Relação entre volume hipocampal e volume de ressecção cirúrgica com controle de crises e desempenho de memória em pacientes com epilepsia de lobo temporal mesial submetidos a tratamento cirúrgico / Relationship between hippocampal volume and surgical resection volume with seizure control and memory performance in patients with mesial temporal lobe epilepsy undergoig surgical treatment
Epilepsy is the second most frequent neurological disease and temporal lobe epilepsy is the most common form of focal epilepsy and is more frequently associated to refractoriness and memory decline. The epileptogenic lesion can be studied through magnetic resonance imaging, EEG and other tests, facilitating the indication of surgery that aims to reduce seizu
