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...

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...

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...

The paper describes clinical cases of concomitant lung and intrathoracic lymph node involvements as evidenced by conventional radiography and computed tomography (CT). It shows difficulties in the differential diagnosis of different nosological entities in pulmonary tuberculosis. The x-ray semiotics of concomitant lung injuries is also depicted.

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...

BACKGROUND: Protein energy malnutrition, a major health and nutritional problem in India, leads to retardation in bone maturity and eventually physical growth. Many studies have been done on ossification centers of hand bones for estimation of skeletal maturation and to diagnose malnutrition but very few studies have been done so far to see effect of protein energy malnutrition on surface area of carpal bones. AIMS AND OBJECTIVES: The surface areas of carpal bones on radiographs on both sides were calculated, analysed and compared in protein energy malnutrition (PEM) cases and healthy controls upto five years of age to see the variability among study groups...

BACKGROUND: Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among females, accounting for 23% of total cancer cases and 14% of cancer deaths worldwide. The developing countries are catching up with this trend. Breast ultrasound when properly performed and interpreted, is an indispensable tool in breast imaging. The early diagnosis and treatment of breast masses reduces the morbidity and mortality associated with delayed diagnosis of breast carcinoma...

Reactive oxygen species (ROS) are generated as a consequence of metabolic reactions in the mitochondria of eukaryotic cells. This work describes the role of the manganese superoxide dismutase (MnSOD) as a biomarker of different human diseases and proposes a new therapeutic application for the prevention of cancer and its treatment. The paper also describes how a new form of human MnSOD was discovered, its initial application, and its clinical potentials. The MnSOD isolated from a human liposarcoma cell line (LSA) was able to kill cancer cells expressing estrogen receptors, but it did not have cytotoxic effects on normal cells...
