Transabdominal sonography comparison with transvaginal sonography

Aims & Objectives: Transvaginal sonography (TVS) comparison with trans-abdominal sonography (TAS) in the diagnosis of pelvic masses Study Design: Retrospective descriptive study conducted at Gynae clinic Jinnah Hospital Lahore with collaboration of radiology department Materials and Methods: Transvaginal Sonogram was compared with transabdominal sonogram in hundred women referred for evaluation of pelvic masses from gynae clinic. All the women were interviewed regarding their age, parity, duration of mass and associated symptoms. Diagnosis was based on the combination of clinical, sonographic (TVS, TAS) and surgical correlation. Both ultrasound modalities were compared for the details about the internal architecture and diagnostic information. Results: Most common age group with pelvic masses was between 26-35yrs. TVS was more sensitive for both uterine and adnexal masses. Sensitivity of TAS was 65% and TVS was 88%. There was a significant difference in diagnosing true positive cases by trans-vaginal approach. (P value < 0.001) Specificity of TAS was 89% and TVS 86% for both uterine and adnexal masses. Image quality was better in 87% of cases with trans-vaginal approach and 5% of cases with trans-abdominal approach and it was equivalent in 8% of cases. There was a significant difference in the image quality between two modalities (P value < 0.001). Regarding anatomical details TAS was better in 12% of cases and TVS was better in 28% of cases and both were equivalent in 60% of cases, Diagnostic information of these two modalities was almost equivalent. TAS was better in 7% of cases and TVS was better in 8% of cases and both were equivalent in 85% of cases Conclusion: The results suggest that TVS has considerable advantage over conventional TAS in evaluation of pelvic masses in women.

Anatomical Information

The use of Cartesian and Blade techniques also affects image quality. The Cartesian technique is more commonly used in Knee MRI examinations. Cartesian technique is vulnerable to movement, giving rise to motion artifacts. This motion artifact is often caused by too long scanning time, so ETL settings are important. An alternative to reducing this risk is to use the Blade technique and by setting the appropriate ETL. The research objective was to determine the differences image quality and anatomical information and to determine the technique that produced quality images and MRI anatomical information on the sagittal knee section between the Cartesian ETL and Blade T2 Weighted TSE combination. This is experiment research. Samples of 10 volunteers, carried out scanning with Cartesian and Blade techniques with variations ETL 14, 16, 18. Focus of assessment on ACL, PCL, meniscus, fluid, and fat. Image quality includes SNR and CNR. The assessment of the anatomical information by a radiologist. Data analyzed with Anova, Friedman, and Wilcoxon test. The results study showed that overall, there are significant differences in image quality between Cartesian and Blade techniques with p-value 0.005. There are differences in anatomical information with p-value <0.001. The best technique from image quality (SNR and CNR) is Cartesian-ETL 14 and based on anatomical information, the best technique is using Blade-ETL 14. Image quality in the two techniques with ETL 14 there is no significant difference with p-value of 0.414, so that Cartesian and Blade-ETL 14 settings produce the same image quality.

ABSTRACT Introduction Point-of-care ultrasound (POCUS) is a tool undergoing expanding use in military medicine, including routine inpatient, outpatient, and operational environments. Specific musculoskeletal POCUS examinations require additional equipment in the form of a standoff assist device to maximize image acquisition. These devices may not be readily available to POCUS users in more austere or resource-constrained environments. We devised a study to determine if intravenous fluid bags of various volumes could be substituted for standard standoff devices in musculoskeletal POCUS. Materials and Methods Sequential images of a soft tissue foreign body model, an interphalangeal joint, and a chest wall were taken using a gel standoff pad or water bath and compared to images acquired using three different sizes of intravenous fluid bags after removing excess air from the bags. Images were de-identified and scored for quality using a visual analog scale. We used a two-factor analysis of variance without replication to analyze the differences in image quality between standoff devices, with a P-value less than.05 considered statistically significant. Results We performed 13 POCUS studies and had a group of eight POCUS-trained physicians and physician assistants score these studies, resulting in 104 total quality scores. There was no significant difference in image quality between standoff devices for chest (P-value.280) and hand (P-value 0.947) images. We found a significant difference in image quality between standoff devices for the soft tissue foreign body model (P-value 0.039), favoring larger intravenous fluid bag standoff over standard devices. Conclusions In the absence of a standard commercial gel standoff device or water bath, intravenous fluid bags of 50, 100, and 250 mL can facilitate quality image acquisition for musculoskeletal POCUS.

Abstract Background Rotator cuff tendinopathy is a leading cause of shoulder pain and a significant source of disability. It is a common disorder, with its prevalence increasing substantially with age and affecting more than 50% of the general population by the age of 60 years Objectives Based on these facts, our study efforts seeked assessment of the role of ultrasound guided platelet rich plasma injection (PRP) in cases of rotator cuff tendinopathy. Patients and Methods Type of Study is single arm interventional study was conducted in Ain shams university hospitals in the period between October 2018 and March 2019, 15 patients were included in the study ranging from 25 to 60 years old, were referred to the Radiology department at Ain Shams University Hospitals. Study Setting: all US examinations were performed by the same senior musculoskeletal radiologist with a large experience in the musculoskeletal US at the radiology department of Ain Shams University hospitals. Study Period: 6 months for data collection. Results Our study showed remarkably noticeable change on comparing the pre-injection and post-injection SPADI Scoring system at 4,8,12 and 24 weeks. There is highly statistically significant pain and disability score and percentage improvement, yet on the other hand the radiological improvement shows no statistically significant difference found between baseline tendon thickness and its follow up at 4, 8 and 12 weeks while only there was statistically significant decrease in tendon thickness found at 24 weeks with p-value = 0.043. Conclusion The ultrasound-guided PRP injection for supraspinatus tendinopathy cases is a safe, cheap, and easily prepared outpatient procedure which showed competitive, promising, and well-proved results when compared to other modalities outcomes such as conventional surgeries, arthroscopic procedures, and physiotherapy. It deserves our attention to its value and efficacy for the sake of the patient as a minimally invasive procedure providing better quality of life.

Abstract Aim of the Work to compare between HHUS and 3D ABUS, according to their benefits and limitations as a complementary scan for mammography in detection of breast lesions. Patients and Methods The study was conducted on 30 female patients with breast masses diagnosed by clinical examination or by sonomammography in Radiology Department at Al Sheikh Zayed Aal Nahian hospital and Ain Shams University Hospitals during the period from October 2018 and August 2019. Findings were confirmed by histopathological biopsy or at least 6 months follow up. Results Statistically significant difference between ABUS and HHUS time of examination in favor of ABUS with P-value >0.0001 and 95%CI-5.7:-4.4, as ABUS time of examination was (mean+/- SD: 4.1 +/-0.9) and HHUS was (mean +/- SD: 9.2 +/-2.0). In this study; 8 out of 30 were malignant lesions and 22 were benign findings. HHUS showed higher sensitivity than ABUS (100% versus 88%); specificity (86%, 91%), positive predictive value (73%, 78%) and negative predictive value (100%, 95%) respectively. HHUS and ABUS shows nearly perfect agreement regarding lesion classification(benign &malignant).with Cohen’s kappa (κ) 0.85, and also regarding BIRADS classification With Weighted kappa 0.824. Conclusion There is a near perfect agreement between ABUS and HHUS diagnostic performance (κ) 0.85,and statistically significant difference in time of examination in favor of ABUS as it is operator independent and provide large scanned area in every single sweep and also aided with computer software, but HHUS still have higher sensitivity than ABUS and that may be attributed to ABUS limitations to evaluate axillary lymph nodes and lack of Doppler, so ABUS may serve as an effective, adjunct, screening tool to mammography and hand held Sonography.

Background: To evaluate the value of time-of-flight MR angiography (TOF MRA) for the assessment of extracranial-intracranial (EC-IC) bypass in Moyamoya disease in comparison with computed tomography angiography (CTA). Patients and methods: A consecutive series of 23 patients with Moyamoya disease were analyzed retrospectively. Twenty three patients underwent 25 procedures of extracranial-intracranial bypass. Cranial CTA was performed within one week after the surgery to assess bypass patency. Then TOF MRA was scanned within 24 h after CTA on a 3T MRI system. Using 5-point scales (0 = poor to 4 = excellent), two radiologists rated the image quality and vessel integrity of bypass for three segments (extracranial, trepanation, intracranial). Results: Image quality was high in both CTA and TOF MRA (mean quality score 3.84 ± 0.37 and 3.8 ± 0.41), without statistical difference (p = 0.66). Mean scores of TOF MRA with respect to bypass visualization were higher than CTA in the intracranial segment (p = 0.026). No significant difference of bypass visualization regarding the extracranial and trepanation segments was found between TOF MRA and CTA (p = 0.66 and p = 0.34, respectively). For the trepanation segment, TOF MRA showed pseudo lesions in 2 of all 25 cases. Conclusions: 3T TOF MRA, a non-contrast technique not exposing the patients to radiation, proved to be at least equal to CTA for the assessment of EC-IC bypass, and even superior to CTA with respect to the intracranial segment. In addition, readers should be aware of a potential overestimation showing focal pseudo lesions of the bypass at the trepanation segment in TOF MRA.

Synthesis of the 4-chlorobenzoylthiourea compound was carried out by acylating thiourea with 4-chlorobenzoyl chloride. The 4-chlorobenzoylthiourea compound will increase the lipophilic and the electronic properties other than the lead compounds of benzoylthiourea in order to, by expectation, raise the central nervous system depressant as well. The lipophilic would affect the ability of the compounds in penetrating biological membranes, which is highly dependent on the solubility of the drug within lipid/water. Log P is the most common method used in determining the parameter value. This experiment was to mix two dissolvents (octanol and water) which are immissible. The both levels of the compounds were carefully observed by a spectrophotometer UV-Vis. From the test, the result of log P value of the 4-chlorobenzoylthiourea compound was 2.32, while the theoretical log P value of the compounds, by using the π Hansch-Fujita method is 1.62 and the f Rekker-Mannhold method is 2.225. Consequently, the result of the test shows that there is a significant difference between the progress experiment and both theoretical log P methods. Moreover, in the test of the central nervous system depressant through the potentiation test to thiopental using mice indicates that the 4-chlorobenzoylthiourea compound have potentiation effects to thiopental compared to the lead compounds of benzoylthiourea.

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

Abstract: Routine blood examination is the earliest blood test or screening test to determine the diagnosis of an abnormality. Blood easily froze if it is outside the body and can be prevented by the addition of anticoagulants, one of which Ethylene Diamine Tetra Acetate (EDTA). Currently available vacuum tubes containing EDTA anticoagulants in the form of K2EDTA and K3EDTA. K3EDTA is usually a salt that has better stability than other EDTA salts because it shows a pH approaching a blood pH of about 6.4. The purpose of this research is to know the difference of erythrocyte index results include MCH, MCV and MCHC using K3EDTA anticoagulant with K2EDTA. This research is a cross sectional design. This study used venous blood samples mixed with K2EDTA anticoagulant and venous blood mixed with K3EDTA anticoagulants, each of 30 samples. Data were collected and analyzed using paired different test. Based on data analysis that has been done on MCH examination, p value <0,05 then there is a significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value. Then on the examination of MCV and MCHC obtained p value <0.05 then there is no significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value.Abstrak: Pemeriksaan darah rutin merupakan pemeriksaan darah yang paling awal atau screening test untuk mengetahui diagnosis suatu kelainan.
