Research Type

Background: There are two image acquisition techniques in MRCP examination, which are breath-hold and trigger technique. Acquisition process in breath hold occurs when the patient holds their breath, meanwhile trigger technique uses respiratory gatting that functioned to monitor patient’s respiration and the acquisition occurs in the transition phase of inspiration and expiration. In Royal Taruma Jakarta Hospital this two technique are used sustainably, but in other hospital, such as Hasan Sadikin Bandung Hospital just uses one technique. This research aims to know the difference of anatomic image information of breath-hold and trigger technique in MRCP examination using T2 HASTE sequence coronal slab and to know which examination technique is better to produce anatomic image information between breath-hold and trigger technique.Methods: This research type was quantitative research with the observational approach. The data obtained by scanning 10 patients using breath-hold and trigger technique in Royal Taruma Jakarta Hospital. The image result was scored by radiology physician using checklist. The obtained data was analyzed with Wilcoxon test to know the difference of anatomic image information and which technique is better to produce anatomic image information between breath-hold and trigger technique.Results: The result showed that there were differences of anatomic image information of breath-hold and trigger technique on MRCP examination using T2 HASTE sequence coronal slab with p-value 0,011. Trigger technique produced better anatomic image information than breath-hold technique.Conclusion: There were differences of anatomic image information of breath hold and trigger technique on MRCP examination using T2 HASTE sequence coronal slab. Trigger technique produced better anatomic image information than breath-hold technique

The Difference

Background: Stroke is a brain disease where an acute nerve function is occurred due to the cerebral vascular disorders. To establish a diagnosis the stroke, it can be identified by employing the Diffusion Weighted Imaging (DWI) sequence in the MRI examination. Artifacts still exist on the MRI image which in turn reduce the resolution when using the DWI sequence. Adding the PROPELLER data acquisition method in the DWI sequence possibly improves the quality of brain images. The purpose of this study is to know the difference on the quality of anatomical image information between the DWI sequences with PROPELLER and without PROPELLER methods, and to determine adequate anatomical image appearance that created in amongst of the two methods, specifically for the stroke disease.Methods: this research is quantitative research with experimental approach. This study was conducted using MRI 1.5 T at Bethesda Hospital Yogyakarta. Data were 16 images from 8 patients using DWI sequences using PROPELLER without PROPELLER on MRI Brain examination with stroke. The results of the image were evaluated on 7 criteria: cortex cerebri, basal ganglia, thalamus, pons, cerebellum, stroke (infarction) and artifacts using questionnaires given to 3 respondents. Data analysis was done by Wilcoxon test to know the difference of anatomical image information on DWI sequence using PROPELLER without PROPELLER and to know better anatomical image information from both sequences seen from mean rank value.Results: The results shown, there is a significant difference on the quality of anatomical image information and the artifacts between the use of DWI sequence with and without PROPELLER methods ( 0.05). Based on the mean rank results, the DWI PROPELLER sequence has a higher mean rank value 4.50 compared to the DWI sequence without PROPELLER 0.00.Conclusions: The DWI PROPELLER sequence has better image results compared to the DWI sequence without PROPELLER.

Background: Brain Magnetic Resonance Venography (MRV) is a MRI examination of veins without contrast media. Phase Contrast (PC) MRV sequences uses phase shift protons that flow along the magnetic gradient into needed area (Field Of View).  PC MRV sequences use bipolar gradient to compensate the proton spin speed by adjusting the amplitude. The study aims to determine the Velocity encoding Value (VENC) to MRV image information on brain tumor patient and to determine the best image information through a technic to visualize the veins in brain tumor patient.Methods: This study was a quantitative study with quasi experimental approach. Data were collected in Radiology Department of Dr. Moewardi Surakarta Hospital on May to June 2016. Data was collected using questionnaire filled by three respondents. Data were analyzed statiscally using Friedman test and Wilcoxon test to determine the difference of value of Velocity Encoding (VENC) between 10 cm/sec, 15 cm/sec, 20 cm/sec, as well the mean rank test used to find out the best image information.Results: The statistical test showed that there were significant differences in image information of MRV, between VENC 10 cm/sec, 15 cm/sec and 20 cm/sec with p value was 0.032 (p˂0,05). The best result of MRV image information was when VENC value of 20 cm/sec used, indicated by the mean rank which was 2.83.Conclusion: There were significant differences of MRV image information between VENC 10 cm/sec, 15 cm/sec and 20 cm/sec. The best result of MRV image information was when VENC value of 20 cm/sec used, to visualize better anatomy of the veins, so that the presence of tumor thrombus in the veins can be ensured.

<em>The aim of this research is to find out the effectiveness of individual counseling through emotive rational counseling approach in overcoming anxiety in Payakumbuh Class IIB Penitentiary. The population is fostered citizens before the criminal period ends as many as 20 people, while the study sample is fostered citizens before the criminal period ends as many as 5 people and who are indicated to have high anxiety based on non-rondom sampling techniques and recommendations from employees. The data collection instrument is a Likert scale. Data analysis techniques using non-parametric statistical tests using Wilcoxon rack test, hypothesis testing using Statistical Product and Service Solution (SPSS) version 22. The results showed the difference between the pretest and posttest values. From the Wilcoxon test calculation results obtained a significant sip-value of 2.023. Based on the applicable provisions, it is known that the Wilcoxon Sig p-value test result is 0.043 &lt;α (α = 0.05) which means that Ha is accepted and Ho is rejected.

Background: Trigeminal neuralgia (TN) is a severe neuropathic unilateral facial pain affecting about 30% percent of the world population. Neuropathic pains are considered to be associated with multiple sclerosis (MS).Multiple sclerosis is a chronic inflammatory condition causing demyelination and degeneration of axons in central nervous system. Objective: The objective of the study is to determine role of Magnetic Resonance Imaging to find association between trigeminal neuralgia and multiple sclerosis. Methods: The prospective cohort study was conducted for six months in Radiology Department of Hayatabad Medical Complex, Peshawar from September 2020 to February 2021. Initially 250 patients were screened for multiple sclerosis. The study recruited a total of 35 patients of MS visited neuroradiology department, out of which 26 patients were enrolled in the study. The participants with age of 18 years and onward of both genders with definitive symptoms of TN with MS that is having unilateral TN pain (that is sharp shooting electric pulse like) lasting for up-to 2minutes precipitated with an environmental stimulus were included in the study. The patients (n=6) with bilateral MS with TN and cognitive disturbances (n=3) were excluded from the study. Results: The study recruited a total of 26 participants with MS related TN. The clinical examination didn’t show any difference between the three groups with the p-value less than 0.001. Age at the onset of MS was younger in patients with MS related sensory disturbances compared to other two groups, with p-value less than 0.05. The frequency of the affected side was different in all three groups with the p-value less than 0.05 as tested by Fischer exact test. Trigeminal reflex tests done for different components such as R1 and SP1 showed longer latency periods for the affected side after stimulation and unaffected side after stimulation with the mean of 14.2± 4.4 and 15.3±3.2, 16.3±4.2 and 17.4±5.2ms and p-value less than 0.001 as shown by Wilcoxon test. Conclusion: The study showed significant association between trigeminal neuralgia and multiple sclerosis with the greater efficacy of using MRI as imaging technique to find this association.
