to differentiate benign from malignant pediatric head and neck masses with a sensitivity of 97.3%, specificity of 80.0%, positive predictive value of 94.7%, and negative predictive value of 88.9%.
Diffusion-weighted MRI study is an accurate, fast, noninvasive, and nonenhanced technique that can be used to characterize head and neck lesions. DWI helps to differentiate malignant from benign lesions based on calculated ADC values. Additionally, DWI is helpful to guide biopsy target sites and decrease the rate of unnecessary invasive procedures.

Newer cardiac magnetic resonance techniques like native T1 mapping are being used increasingly as an adjunct to diagnose myocardial diseases with fibrosis. However, its full clinical utility has not been tested extensively, especially in the Indian population. The purpose of this study was to find native T1 values in healthy individuals without cardiac disease in our 3-Tesla MRI system and examine whether native myocardial T1 values can be used to differentiate between normal and diffuse myocardial disease groups.
After approval from the institutional ethics committee, native T1 mapping was performed in 12 healthy individuals without cardiac disease who served as controls and in 26 patients with diffuse myocardial diseases (acute myocarditis (
= 5), hypertrophic cardiomyopathy (HCM) (
= 8), nonischemic dilated cardiomyopathy (DCM) (
= 7), restrictive cardiomyopathy (RCM) due to amyloidosis (
= 6)) in a 3-Tesla MRI system in short axis slices and four-chamber view using a modified Look-Locker inverffuse myocardial disease groups.
Coronary artery disease (CAD) is a major cause of morbidity and mortality in India. Stress Cardiac Magnetic Resonance (CMR) using vasodilator agent is well established in assessing the functional significance of CAD. Adenosine is the preferred agent, but can have severe side effects including dyspnoea, chest pain, atrioventricular block or bronchospasm. The stress CMR examination is not routinely performed in many of the clinical imaging departments in India.
The aim of this study was to establish safety of adenosine as a pharmacological stressor agent for CMR in a tertiary care radiology department in India.
A review of all patients undergoing stress CMR in our institution from May 2018 to May 2019 was made. Records were reviewed to collect response parameters and documented adverse reactions.
A total of 1057 patients underwent stress CMR during this period. No death, myocardial infarction or atrio-ventricular block related complications were seen. Transient hypotension was seen in 20 patients (1.8')a fully equipped and well-trained radiology department in India.
An intracranial aneurysm (IA) is a life-threatening condition and endovascular treatment (EVT) is a demanding procedure, especially in IAs with an unfavorable anatomy. The aim of this study was to investigate the safety and efficacy of balloon-assisted microwire navigation and microcatheter positioning in the EVT of IAs with challenging anatomies.
This retrospective study included patients that underwent balloon-assisted microwire navigation and microcatheter positioning in the EVT of IAs between September 2016 and January 2019. All EVT procedures and data collection were performed by the same two neurointerventional radiologists. Technical success and complication rates, safety, and efficiency of the balloon manipulation method were evaluated. Statistical software was used to analyze the basic descriptive data of the patients and aneurysms.
This study included 14 patients. The microwire navigation of the target artery with balloon manipulation was used in 4 aneurysms of 4 patients. Microcatheter positioning with balloon manipulation was used in 10 aneurysms of 10 patients. There was no complication caused by the balloon manipulation technique. The technical success rate was 100%.
In the EVT of IAs with challenging anatomies, the presented technique is a safe and effective option without additional complications, especially in the target artery with an acute angle and in small aneurysms.

Iliolumbar syndrome is a frequent cause of chronic nonspecific low back pain. The cornerstone of its treatment lies upon the specific diagnosis of the iliolumbar syndrome. read more The ultrasound guided interventions have the potential for the specific diagnosis and treatment of the iliolumbar syndrome.
To assess the role of ultrasound-guided intervention for the diagnosis and treatment of the iliolumbar syndrome.
The study comprised of fifty-seven patients of nonspecific low back pain with the clinically suspected iliolumbar syndrome. Two-staged ultrasound-guided interventions were performed Primary diagnostic and secondary therapeutic interventions. Favorable response after the injection of local anesthetic agent in iliolumbar ligament (defined as VAS score to ≥3) was classified as confirmed Ilio-lumbar syndrome. Clinico radiological efficacy after platelet-rich plasma (PRP) injection in confirmed iliolumbar syndrome patients was done.
Out of 57 patients, 45 (78.95%) were diagnosed with confirmed Iliolumbar syndrome after primary diagnostic intervention. The mean value of VAS at presentation was 8.02 ± 0.72 which was decreased to 3.16 ± 1.63;
< 0.0001. All 45 patients underwent PRP injection in iliolumbar ligament and 42 patients (93.33%) showed reduction in mean VAS score from 8 ± 0.67 (at presentation) to 0.89 ± 1.23 after 6 weeks follow up;
< 0.0001. Iliolumbar ligament thickness was decreased from the day of presentation (2.66 ± 0.22) to 6 weeks after therapeutic intervention (0.91 ± 0.42);
< 0.0001.
The ultrasound guided diagnostic and therapeutic intervention were found to result in a specific diagnosis and remarkable recovery in the iliolumbar syndrome group of nonspecific low back pain patients.
