Scintigraphic findings and parameters at diagnosis, including thyroid stimulating hormone (TSH), free thyroxine (fT4), gender, and gestational age, were reviewed. The need for lifelong thyroxine replacement therapy was reviewed.Results: The study included 85 subjects, with 74 (87.1%) presenting with eutopic thyroid and 11 (12.9%) showing thyroid dysgenesis. Patients with scintigraphic evidence of thyroid dysgenesis required permanent thyroid hormone replacement therapy. Among the patients with eutopic thyroid, a higher TSH level was associated with the need for lifelong thyroid hormone replacement therapy (cutoff TSH value 18.72 mIU/L, sensitivity 77.3% and specificity 53.8%). Gender, gestational age, and fT4 did not show significant differences between the transient and permanent CH groups in patients with eutopic thyroid.Conclusion: Scintigraphic findings of thyroid dysgenesis indicate a high prevalence of permanent CH. In patients with eutopic thyroid, higher TSH levels predict the requirement for lifelong thyroid hormone replacement therapy. These results provide insights into the prediction of CH and aid in individualized treatment decisions for patients with CH.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"15 ","pages":"3"},"PeriodicalIF":1.1,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11801473/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143364974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All these patients underwent dynamic contrast CT during both inspiration and expiration for adrenal venous sampling purposes. Two experienced radiologists measured the aortomesenteric angle during both end-inspiration and end-expiration, and its variation rate. Pearson's or Spearman's correlation analysis was used to assess correlations between the angle or variation rate and height, weight, body mass index (BMI), visceral fat, subcutaneous fat, and diaphragm motion.Results: The aortomesenteric angle was significantly larger at end-expiration (88.65 ± 25.15, 95% confidence interval [CI] 82.09-95.20) compared to end-inspiration (62.22 ± 21.90, 95% CI 56.51-67.93, P < 0.001).

The aim is to explore the relationship between peak enhancement time (PET) and various parameters during CHD assessment with CCT.Material and methods: The study involved 38 CHD patients undergoing CCT, with observations made on their heart rate, respiratory rate, saturation, cardiac output, weight, height, and age. The PET for each case was determined, and Spearman's rank correlation was employed to evaluate the association between these parameters and the PET.Results: The median PET was 20.63 s, with a mean aortic Hounsfield unit of 512.16 ± 160.56. A moderate negative correlation was found between PET and both heart rates (r = -0.42, P = 0.009) and respiratory rates (r = -0.41, P = 0.01), whereas a negligible positive correlation (r = 0.19, P = 0.25) was observed with SpO2. A moderate positive correlation was noted between PET and both weight (r = 0.44, P = 0.005) and height (r = 0.40, P = 0.01). In addition, there were significant differences in median PET across different age categories.Conclusion: The findings conclude that PET during CCT is significantly associated with heart rate and respiratory rate. An increase in these rates corresponds to a notable decrease in PET. Consequently, the study recommends minimizing scan delays in CCT for patients exhibiting higher heart rates.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"14 ","pages":"50"},"PeriodicalIF":1.1,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11704290/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This synergy has significantly enhanced surgical planning, fostered the creation of tailor-made medical apparatus, bolstered medical pedagogy, and refined targeted therapeutic delivery. This review delves into the contemporary advancements and applications of 3D printing in neuroradiology, underscoring its pivotal role in refining surgical strategies, augmenting patient outcomes, and diminishing procedural risks. It further articulates the utility of 3D-printed anatomical models for enriched comprehension, simulation, and educational endeavors. In addition, it illuminates the horizon of bespoke medical devices and prosthetics, illustrating their utility in addressing specific cranial and spinal anomalies. This narrative extends to scrutinize how 3D printing underpins precision medicine by offering customized drug delivery mechanisms and therapies tailored to the patient's unique medical blueprint. It navigates through the inherent challenges of 3D printing, including the financial implications, the need for procedural standardization, and the assurance of quality. Prospective trajectories and burgeoning avenues, such as material and technological innovations, the confluence with artificial intelligence, and the broadening scope of 3D printing in neurosurgical applications, are explored. Despite existing hurdles, the fusion of 3D printing with neuroradiology heralds a transformative era in precision medicine, poised to elevate patient care standards and pioneer novel surgical paradigms.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"14 ","pages":"49"},"PeriodicalIF":1.1,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11704292/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a 71-year-old male with a history of dyspnea on exertion with baseline wall motion abnormality on a transthoracic stress echocardiography irreversible after exercise. Coronary computed tomography angiography revealed a dual LAD system: The left short LAD (LAD1) originating from the left main coronary artery and the right LAD (LAD2) arising separately from the right coronary cusp, distinct from the right coronary artery ostium. Having different origins and courses, both LADs supply the LAD territory. Our case is notable for two main reasons: The rarity of this particular type of dual LAD anatomy and the unique course of the LAD2, which, to our knowledge, has not been described in any previous case report. Although rare, dual LAD coronary artery should be considered in patients with atypical short LAD.

Our goal was to evaluate a cohort of patients with myocardial infarctions visible on cardiac magnetic resonance imaging (MRI) to determine how often the area of infarction was retrospectively visible by preceding, conventional CT. We also sought to evaluate how often the diagnosis of myocardial infarction was reported at the time of initial study review.Material and methods: The Institutional Review Board approval was obtained for the creation and retrospective analysis of a database of patients undergoing cardiac MRI. We started with a cohort of 252 patients who had undergone cardiac MRI at our institution, over a 4-year period. We identified 160 patients who had a myocardial infarct visible on MRI.Results: Of the 160 patients who had been identified as having an infarct on cardiac MRI, 54 patients had undergone a recent (within 30 days) conventional CT scan, usually done for non-cardiac indications. In addition to the review of reports, non-cardiac CT scans were also evaluated retrospectively by two experienced, cardiothoracic imaging physicians, including a radiologist and a cardiologist. In 26 of these patients (48.1%), an infarct was visible on the CT images. In 12 of these 26 cases (46.1%), the infarct was noted in the initial report. In the remaining 14 of these 26 cases (53.8%), the infarct was unrecognized at the time of initial study interpretation.Conclusion: Our retrospective analysis demonstrates that myocardial infarctions may be frequently observed on non-gated, non-cardiac CT scans but may be underrecognized and under-reported.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"14 ","pages":"45"},"PeriodicalIF":1.1,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11618727/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142785871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
