Introduction: Anatomical variation of the colon can cause diagnostic dilemmas and pose a problem while radiological interpretation and during various procedures. Radiologists and clinicians should exert much caution during the procedures in such patients. This study was done to study the anatomical variation of the colon in abdominal CT scans and correlated the variations with gender. Methods: It was a cross-sectional study done at the Department of Radiology and Imaging of Manipal Teaching Hospital from September 2020 to March 2021. Abdominal CT was obtained and colonic position was evaluated. The Chi-square test was applied to assess the correlation between colonic variations and gender. Results: There were 388 patients in total. The age of the patients ranged from 3 years to 94 years. The mean age of the patients was 44.8±18.6 years. There were 166 (42.8%) females and 222 (57.2 %) males. Out of 388 patients, 170(43.8) had some colonic anatomical variations. Sixteen (4.1%) patients had retro gastric colon. Around 6% had a right retrorenal colon and 30(7.7%) had a left retrorenal colon. Seven (1.8%) patients had anterolateral hepatodiaphragmatic interposition. Forty-two patients (10.8%) had high positioned caecum. The redundant sigmoid colon was present in 38(9.8%) patients. There was no significant correlation between the colonic variation and gender. Conclusion: Different variations in the colon exist even in the Nepalese population, of which the radiologists, as well as the surgeons, should be aware.

Introduction: Determination of fetal weight is important for the management during labour and delivery. It helps in determining the mode of delivery and aids in diagnosing low birth weight, macrosomia, and intrauterine growth restriction fetus. Ultrasound may not be available in under-resourced settings. Therefore, it is important to study the accuracy of clinical estimation of fetal weight with the sonographic and actual birth weight. Methods: One hundred and fifty women fulfilling the inclusion criteria were enrolled for the study. Clinical estimation of fetal weight was done by using the Johnson formula. Then the women were subjected to ultrasound. Sonographic estimation of fetal weight was done by the Hadlock method. The two estimated fetal weights were then compared with the actual birth weight. Data were analyzed using SPSS (VERSION 16). Results: Actual birth weight has a strong correlation with the ultrasonographic birth weight (p=0.01). However, the clinical birth weight estimation was less correlating to the actual birth weight (p=0.638) Conclusion: The ultrasound method is better in determining the actual birth weight as compared to the clinical method. Hence, ultrasound has to be recommended whenever available.

Introduction: Cervical spinal stenosis has been established as a predisposing factor of cervical myelopathy and is associated with cord injury. Space available for the cord (SAC) can be used as an indicator of spinal stenosis. Methods: This study was performed on patients referred for MRI examinations of the cervical spine for various clinical indications to a tertiary centre in Nepal. Data were collected for a period of four months from January to April after IRB approval. Convenience sampling was employed and a total of 72 examinations were included. Data were obtained from the 1.5T Magnetom Amira Siemens MRI scanner. Sagittal diameters of the spinal canal and spinal cord were traced and measured from C3 to the C7 vertebra. The space available for the spinal cord (SAC) was calculated by subtracting the sagittal cord diameter from the corresponding sagittal canal diameter. Results: The average space available for cord was 4.48mm±1.04mm at C3, 4.44mm±1.03mm at C4, 4.63mm±1.01mm at C5, 5.11mm±1.07mm at C6, 5.87mm±1.14mm at C7 vertebral level. The SAC value was not significant according to gender and age (p>0.05). Conclusions: The smallest SAC value was detected at the C4 vertebral level with a mean value of 4.44mm and the greatest value was at C7 vertebral level with a mean value of 5.87mm. There was no significant gender difference in SAC values.

Introduction: Percutaneous renal biopsy is done under ultrasonographic guidance in recent times due to which the diagnostic yield has increased and complications have been severely curtailed. We aimed to retrospectively evaluate the complications following kidney biopsy in children. Methods: After obtaining ethical clearance, retrospective evaluation of sixty pediatric renal biopsies done in BPKIHS from October 1, 2018, to September 30, 2020, were included in the study. Biopsies were done by 18G biopsy guns under ultrasound guidance and the complications were evaluated. Results: Of sixty patients, 13.33% had gross hematuria, 3.33% had a perirenal hematoma and the biopsy failure rate was 3.3%. None of the patients required blood transfusion and had major complications requiring further intervention. Conclusions: Percutaneous renal biopsy under ultrasonographic guidance is a safe procedure with a better success rate.

Introduction: Low back pain secondary to degenerative disc disease is a condition that affects young to middle-aged persons with peak incidence at approximately 30-39 years. Magnetic Resonance Imaging (MRI) is the standard modality for detecting disc pathology. This study is being conducted to review the pattern of spinal degenerative diseases in patients referred to our institution. Methods: A retrospective study was conducted at Gandaki Medical College Teaching Hospital & Research Centre (GMCTHRC) from January 2018 to April 2018 with approval from the Institutional Review Committee of Gandaki Medical College Teaching Hospital and Research Centre. The MRI findings were noted i.e. disc desiccation, disc bulge (diffuse, symmetrical and asymmetrical), disc protrusion, neural foramen narrowing, traversing nerve root compression, exiting nerve root compression and posterior annular ligament tear. Results: Out of 98 patients enrolled in the study mean age being 41 years. Disc bulge as most common finding seen in 89 (90.8%) followed by protrusion 50 (51.1%) neural foraminal narrowing (NFN) 72 (73.4%) traversing nerve roots (TNR) compression 58 (59.1%) and exiting nerve root (ENR) compression 22 (22.4%). Conclusions: The study shows that degenerative disc diseases remain the cause of morbidity in the most productive years of life (30-40 years). Large volumes of MRIs performed for this condition represent a significant economic and healthcare burden in a developing country like Nepal.

Introduction: In an ectopic pregnancy, most patients present with 5 to 9 weeks of amenorrhea, mild pelvic pain and vaginal spotting which triggers the evaluation of ectopic pregnancy. The presence of an extrauterine gestational sac containing a yolk sac or embryo is the most specific sonographic finding whereas an echogenic tubal ring in the adnexa is the most common finding.1 This study aimed to find the accuracy of ultrasound findings versus clinical presentation, intraoperative findings and histological findings. Methods: This is a retrospective study. All patients with histopathological diagnoses of ectopic pregnancy were included in the study and data regarding clinical diagnosis, ultrasound diagnosis and intraoperative diagnosis were retrieved and compared with their histopathological diagnosis. Result: There were 216 cases of ectopic pregnancy with an overall incidence of ectopic pregnancy was 0.88%. The sensitivity with ultrasound diagnosis was 99.52% and specificity 11.11% with positive and negative predictive values were 96.2 % and 50 % respectively and overall diagnostic accuracy of 95.83%. The sensitivity was 97.6% and specificity was 11.1% for clinical diagnosis of ectopic pregnancy. The sensitivity was 100% for intraoperative diagnosis of ectopic pregnancy with a positive predictive value is 95.83%. Conclusion: Clinical diagnosis, intraoperative findings and ultrasound findings were highly sensitive to detecting ectopic pregnancy in the study population. The overall diagnostic accuracy was highest for the ultrasound finding.

Computerized Tomography(CT) scan plays an important role in the diagnosis and treatment of sinus and skull base lesions. The CT image distinctly provides detail of bony anatomy, anatomical variation, and the extent of diseases, and differentiates between inflammatory, benign, and malignant sinus and skull base pathology.1 It is an important aspect of imaging that helps not only the diagnostic role but also rules out other sinus pathology and helps in designing the surgical plan by 3D-MPR and 3D VRT CT scan. Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases. It can be associated with sinusitis. The patient may present either with a unilateral headache that is difficult to differentiate from a migraine or often no symptoms which are diagnosed by chance during a radiological examination. Here we present a case of a 42-year female present with left frontal headache and facial fullness treated with endoscopic and open approaches which were designed by CT paranasal sinus 3-D multiplanar reconstruction(3D-MPR) and from 3-D MPR and volume rendering technique(3D VRT).

Introduction: With the advancement of conventional radiography to digital, digital radiography of the chest is commonly performed these days. The role and importance of diagnostic quality of radiographs are to help the radiologists and the clinicians in the diagnosis of diseases and their management, as well as to prevent the misdiagnosis of any pathology. This study was an attempt to quantify the diagnostic quality of chest radiographs by evaluating the quality of depiction of the anatomical details as well as other technical factors. Method: A total of 450 chest radiographs, produced at Tribhuvan University Teaching Hospital, were selected for study over two months period. Five image quality criteria i.e. anatomical coverage, rotation, adequate penetration, adequate inspiration, and scapula out of lung fields were evaluated and tabulated. Results: Out of the 450 radiographs taken for study, only 22.2% of the radiographs fulfilled all the image quality criteria, the rest 77.8% either lacked one or more of the quality criteria. Conclusion: Many technical factors affect the image quality of digital chest radiographs. However, the radiographer/technologist should always try to maintain adequate image quality of the radiographs.
