Fractional anisotropy and apparent diffusion coefficient have been used to quantify the degree of axonal damage and demyelination. The study aims to assess the role of diffusion tensor parameters in detecting early myelopathic changes and correlate them with clinical findings.\u0000Methods: This cross-sectional prospective study including 60 patients with clinical history of cervical myelopathy was carried out at the Department of Radiology from June 2021 to July 2022. Nurick score was used to assess the severity clinically and diffusion tensor images of the cervical spine were obtained using 3 Tesla MRI. These diffusion tensor values at the level of maximum stenosis were compared with those of the non-stenotic level. A correlation between the diffusion tensor parameters and clinical Nurick score was done.\u0000Results: The fractional anisotropy values were significantly lower (0.51 ± 0.14 vs 0.76 ± 0.47) and apparent diffusion coefficient values were significantly higher (1.20 ± 0.20 vs 1.04 ± 0.12) at the level of maximum stenosis compared with non-stenotic levels. There was a moderate positive and strong negative correlation between the apparent diffusion coefficient and fractional anisotropy values with the Nurick score.\u0000Conclusions: A significant reduction in the fractional anisotropy and an increase in apparent diffusion coefficient values at the level of stenosis was observed in individuals without a high T2 signal within the cord.

Ultrasound elastography is a dynamic technique that estimates tissue stiffness to differentiate between benign and malignant masses. Our study aimed to determine and compare the diagnostic accuracy of B mode Sonography, Elasticity contrast index, and Tsukuba score in differentiating malignant and benign breast masses.\u0000Methods: This was a prospective cross-sectional study done including 110 lesions in 102 patients in the age group of 15-73 years. The solid breast lesions seen on sonography were categorized according to the American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) and further evaluated with elastography using both Elasticity Contrast Index (ECI) and Tsukuba score with pathological diagnosis taken as the gold standard. The cut-off value of ECI was obtained. The diagnostic accuracy of B-mode sonography, ECI, and Tsukuba score was compared.\u0000Results: We found that B-mode sonography had a sensitivity of 85.7%, specificity of 100%, and accuracy of 96.9 %. The accuracy of Tsukuba scores for differentiating benign and malignant lesions was 81.2%. The cut-off value of ECI obtained was 2.8 and the accuracy was 81.8%. A statistically significant correlation (p < 0.05) existed between sonographic diagnosis, ECI, and Tsukuba score.\u0000Conclusions: B mode sonography had the highest diagnostic accuracy while ECI and Tsukuba scores were comparable. ECI can be used for breast masses using a cut-off of 2.8 to differentiate benign from malignant.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"19 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140658336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Degenerative changes in the lumbar spine are associated with the alteration of the thickness of the Ligamentum Flavum (LF), which predisposes to clinical symptoms.\u0000Methods: This was a prospective study conducted among ninety symptomatic (LBP) patients who underwent magnetic resonance imaging (MRI) and the images were evaluated to measure the thickness of the LF and evaluate the degree of disc degeneration by the Pfirrmann grading system, according to the spinal levels (L4-L5, L5-S1). An association was sought between LF hypertrophy and disc degeneration, age, sex, and disc height.\u0000Results: The result of this study showed that with increasing age thickening of the LF could lead to degeneration of the intervertebral disc. Thickening of the LF was more at the level of L4-L5 level than at the L5-S1 level with right-sided increased thickness more than on the left and is associated with increased grade of disc degeneration. Females had slightly more thickened LF than the males at the L4-L5 level with no gender predominance at the L5-S1 level.\u0000Conclusions: Thickening of the ligamentum flavum may be an important factor in the origin of LBP, especially in the adult population. A degenerative process in the ligamentum flavum that occurs with age and also suggests the thickening of LF due to mechanical stress at the lumbar level would ultimately result in degeneration of the disc.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"40 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140656985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While clinical diagnosis is essential, imaging evaluation can help confirm lung lesions, their extent, and associated abnormalities. However, radiation exposure from imaging modalities such as Computed Tomography (CT) and Chest X-ray (CXR) is a concern, particularly for neonates. This study aims to identify the various CXR findings in neonates with respiratory distress in the NICU.\u0000Methods: A quantitative cross-sectional study was conducted on 59 neonates with respiratory distress in the NICU from November 2019 to November 2020. Ethical clearance was obtained, and data were collected through portable CXR. The collected data were analyzed using Microsoft Excel 2016 and Statistical Package of Social Services (SPSS) IBM version 23.\u0000Results: CXR findings of 59 neonates with a mean age of 15.9 ± 7.4 days were evaluated. The majority were premature neonates, and the most common clinical diagnosis was respiratory distress syndrome (RDS). Hypoaeration was the most common finding in lung fields, followed by normal aeration. Parenchymal changes were observed in most cases, with reticulations/haziness being the most common, followed by consolidation. Pleural effusion was seen in a few cases, predominantly in preterm neonates with RDS.\u0000Conclusions: The study underscores the prevalence of hypoaeration, reticulations, and consolidations in NICU patients with RDS, emphasizing the importance of early diagnosis and future research in neonatal chest imaging for respiratory distress.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"25 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140657802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ruptured HCC carries a high mortality if untreated. Peripherally located HCC has a higher risk of rupture. However, most of the ruptured HCCs on presentation are in an advanced stage and, hence are unresectable. Henceforth treatment options available are conservative and transcatheter embolization. Methods: Retrospectively, 8 patients with ruptured HCC who underwent trans arterial embolization were studied for hemostasis and 30-day mortality. Clinical history and laboratory data were obtained from the medical records of the patients, and radiological images were extracted from picture archiving and communication systems and studied. Results: The age ranged between 31 to 78 years and 7 were male. In patients presenting with sudden onset pain abdomen, ruptured HCC was suspected if there was a hemoperitoneum with or without extravasation of contrast adjacent to peripherally located HCC on CT angiography. Angiography revealed tumour blush with sentinel vessels in all. Two showed active contrast extravasation. Seven patients with relatively preserved liver function (Child A and B) attained both radiological and clinical hemostasis. One patient with Child C status died due to MODS on day 3 of embolisation. Three patients survived more than a year with additional liver-directed therapies. Two patients were lost to follow-up after discharge and two after six months. Conclusions: Transarterial embolization for ruptured HCC is an effective method of hemostasis and helps in achieving better survival by the additional benefit of tumor control and poor functional status of the liver predicts lower survival.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"75 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139239084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
