Normal range of liver size helps to diagnose hepatomegaly sonologically which may be clinically inapparent.

The liver was measured in right midclavicular line from hepatic dome to lower hepatic margin.  The correlation between liver size and age, sex, weight, height, body mass index (BMI), and body surface area(BSA) was calculated.  The data were properly analyzed in  SPSS version 20 software.\u0000Results: Out of 400 patients, a male: female ratio of 1:1.25, and the age group was ranging from 20 years to 83 years with a mean age of 48.10±14.86 years were included. The mean liver length in males was  15.05 ± 0.27 cms,  females were 14.32 ± 0.29 cms and the total population was 14.73 ±0.46 cms. There was a strong statistically significant correlation between liver size and height, weight whereas the correlation between liver span and BSA was moderate to weak but significant.  Similarly, there was a weak but significant correlation between liver size and BMI with no significant association between liver size and age.\u0000Conclusion:  Accurate assessment of liver size is of utmost importance in the evaluation of suspected hepatic pathologies.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114809392","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}

It can determine the morphological and vascular nature of lymphadenopathies which will further help in the differentiation between benign and malignant nodes.\u0000Methods: This study was conducted on 61 patients referred to the Department of radiodiagnosis and imaging of BiratMedcical College for an ultrasound of cervical lymphadenopathy. These patients had subsequently undergone FNAC examination. Color Doppler sonographic procedures were done with an 11L linear probe with a frequency of 4.5-12MHz and CDUS evaluation of lymph nodes for Resistive Index and Peak systolic velocity were carried out and correlated with FNAC findings.\u0000Results: Among 61 lymph nodes, 52 were benign and 9 were malignant in the Color Doppler study where the final diagnosis by FNAC showed 53 benign and 8 malignant nodes.

The tibiofemoral articulations are separated by articular cartilages and menisci; with little contributions from cruciate ligaments.

Magnetic resonance imaging (MRI) due to its inherent soft tissue contrast is a very good tool to diagnose the condition and look for its extent and deformities.

All MRI studies of the spine performed in a patient with diagnosed spinal tuberculosis during the study period were included in the study. Patients lacking microbiological or pathological diagnoses of spinal tuberculosis were excluded from the study.\u0000Results: A total of 70 patients were included in the study. The mean age of the patients was 45.6 ± 16.8 years. All patients in the study had a spondylodiscitis pattern of involvement. Single intervertebral disc and adjacent vertebrae were involved in 85.7% and multiple contiguous vertebrae and IV discs were involved in 14.3% of cases. Gibbus deformity was seen in 17.1% of cases. Pre/paravertebral and Epidural collections were seen in 95.7% and 72.9% of patients respectively, whereas psoas abscess was seen in 28.6% of patients. Cord compression with myelopathy was seen in 8.6% of patients.
