INTRODUCTION: Magnetic Resonance Imaging (MRI) of adult female pelvis is a well-established tool in the evaluation of utero-ovarian lesions and is often used to supplement ultrasonography. The need for diagnostic surgical intervention has largely been eclipsed with the advent of MRI, which has become the imaging modality of choice for characterization of pelvic masses. AIM: To assess the role of MRI in female pelvic mass lesions and to exploit the tissue characterization capability of MRI...

INTRODUCTION: Artifacts in cone-beam computed tomographic (CBCT) imaging may compromise radiodiagnosis. Obturation materials for endodontic treatment may present with variable material density and thus also cause distinct artifact expression. The aim of this study was to assess the volume distortion artifact of root canal sealers using CBCT devices and micro-CT imaging as a reference. METHODS: Thirty single-root mandibular central incisors were used for this study...

INTRODUCTION: Carcinoma cervix is widely prevalent among women in developing countries. Post contrast Magnetic Resonance Imaging (MRI) utilising spin echo T1 weighted sequence with fat suppression is widely practiced as part of evaluation of carcinoma cervix. However, it is unclear if such post contrast imaging provides any additional information other than adding to the cost of imaging. AIM: To find accuracy of T1 and T2 weighted non contrast MRI protocol in comparison with post contrast spin echo T1 weighted fat suppressed imaging in evaluating the local extent of the carcinoma cervix...

Aneurysms of visceral arteries appear to belong to rare and potentially lethal vascular diseases. The most important role in the aetiology of aneurysms of the gastroduodenal artery is plaid by either acute or chronic pancreatitis. The article deals with a clinical case report concerning a saccular partially thrombosed aneurysm having developed in a 77-year-old woman presenting with the postcholecystectomic syndrome and detected on ultrasonographic examination of the abdominal-cavity vessels. Timely radiodiagnosis (SCT angiography of abdominal cavity vessels), adequate and timely performed endovascular occlusion of the cavity of the aneurysm with metal spirals performed in a timely manner made it possible to attain a favourable outcome...

BACKGROUND: An accessory anteromedial portal (AAMP) has been shown to be effective in placing an anatomically ideal femoral tunnel. It is well known that this is due to the independent femoral drilling which is possible with the AAMP. However very little is known regarding the significance of this reconstruction technique in influencing the functional outcomes of anatomic anterior cruciate ligament reconstruction (ACLR). This study documents the influence of tibial and femoral tunnel positions on functional outcomes of anatomic ACLR using the AAMP...

BACKGROUND: Low back pain (LBP) is the most common symptom which is associated with limitation of normal activities and work-related disability. Imaging techniques are often essential in making the correct diagnosis for prompt management. Plain Radiography though remain a first imaging modality, magnetic resonance imaging (MRI) due to its inherent softtissue contrast resolution and lack of ionizing radiation remains invaluable modality in the evaluation of LBP. AIM: To find the common causes of LBP in different age groups and the role of MRI in detecting the spectrum of various pathological findings...

REVIEW
Victor Puntes
The potential use of nanoparticles (NPs) in medicine is determined by the pharmacokinetical and biodistribution aspects that govern NP behaviour. In this context, diagnosis (low irradiation dose) and therapy (high irradiation dose) is about the same for the NP, as much as to deliver toxic doses of radiation or toxic doses of a chemotherapeutic agent. The NP effects also have to be correlated with how they interact, evolve and are transformed during their exposure to the human body, during their administration, distribution, metabolization and expulsion...

OBJECTIVES: To present a National Registry of patients with prostate cancer as monitored through active surveillance, with the intention of testing the hypothesis that cancer-specific mortality in very low-risk and low-risk patients is less than 5% at 15 years. MATERIAL AND METHODS: A multicentre observational study (AEU-PIEM/2014/0001) sponsored by the Spanish Association of Urology was conducted using their platform for multicentre studies. The clinical-pathological inclusion criteria were as follows: cT1a-cT3a, PSA ≤ 20 ng/ml, initial minimum biopsy of 10 cores, number of affected cores ≤ 3, 1st Gleason score of 3 and 2nd Gleason score ≤ 4 and a known prostate volume (in cc)...

INTRODUCTION: Takayasu's arteritis is a systemic vasculitis that affects the aorta and its main branches mainly seen in young women and it is characterized by decrease or absence of pulses. The arteriography is necessary to corroborate the diagnosis. The aim of this article is to analyze the clinical manifestations and radiological findings in patients with no previous diagnosis of TA. METHODS: The patients were sent to the Department of Radiodiagnosis and Imaging for the performance of an angiography for cerebrovascular disease (CVD) in young patients, renovascular hypertension (RVH) and arterial insufficiency (IA) of limbs...

OBJECTIVE: To optimize a whole-body magnetic resonance imaging (WBMRI) protocol including diffusion-weighted imaging (DWI) used as a diagnostic complex for Hodgkin lymphoma (HL). MATERIAL AND METHODS: The WBMRI protocol adapted for HL staging and monitoring was tried out on 1.5 T and 3.0 T MRI scanners. The investigation included 128 patients with HL verified by complex clinical, laboratory, and instrumental studies (including computed tomography (CT), positron emission tomography (PET), PET/CT, scintigraphy and radiology of the skeleton, ultrasonography, laboratory tests, and biopsy) and 27 healthy individuals...

REVIEW
Zsuzsanna Monostori
In recent years there have been significant changes in the management of lung cancer. In 2009 a new staging system became effective while in 2011 a new adenocarcinoma classification was introduced. Molecular biology, genetics with hybrid multimodal imaging progressed greatly. New biopsy needles were developed for the histological analysis in molecular pathology. Role of LDCT screening in early diagnosis of lung cancer became evident and working groups put it into practice. Integrated and multiparametric devices facilitate more accurate patient follow-up with new biomarkers and newly developed contrast materials...

OBJECTIVE: To improve radiodiagnosis of polyarthropathies. MATERIALS AND METHODS: Three hundred patients aged 18 to 55 years with polyarthropathies were examined. All the patients underwent X-ray study of affected joints and magnetic resonance imaging (MRI). Multislice spiral computed tomography (MSCT) was carried out in 86 patients. Contrast-enhanced MRI was performed in 44 (14.7%) patients. RESULTS. X-ray study and MSCT generally revealed changes involving the bony structures of the joints...

CONTEXT: Urolithiasis remains a major health problem despite advances in therapy. Obstruction results in an increase in pressure within the urinary tract, causing structural and physiologic changes. This study aimed to calculate the intra renal Resistivity Index (RI) of acutely obstructed kidney, to determine the significance of Resistivity Index Ratio (RIR) and difference in Resistivity Index of obstructed and contralateral non obstructed kidney. MATERIALS AND METHODS: Prospective study with renal Doppler for patients presenting with acute unilateral ureteric obstruction...

A twenty-year-old second gravida presented to the department of radiodiagnosis for routine obstetric ultrasound examination. Ultrasonography revealed a live fetus of 17 weeks with absent falx, fused thalami, monoventricle, proboscis, and cyclopia. Fetal MRI was performed and the findings were confirmed. Even though ultrasonography is diagnostic in the detection of fetal anomalies, MRI plays a vital role due to its multiplanar capability and excellent soft tissue resolution. The importance of presenting this classical case of alobar holoprosencephaly is to sensitize the clinicians and radiologists to the imaging manifestations of holoprosencephaly and to stress the importance of early diagnosis...
