Ziessman1 1Division of Nuclear Medicine, The Russell H. Morgan Department of Radiology and Radiological Science, Johns Hop- kins University, Baltimore, MD, USA 2Current Address: Department of Radiology, University of Alabama, Birmingham, AL, USA Abstract: We present our initial two year clinical experience with SPECT/CT, compare the interpretation to SPECT alone, provide illustrative cases, and review the published literature. Hybrid SPECT/CT has added clinical value over SPECT imaging alone primarily due to more precise anatomical lesion localization. After reading this report, the reader will appreciate the advantages of SPECT/CT imaging for clinical practice. We have reviewed SPECT/CT studies of 144 adult patients referred for various clinical indications in a busy nuclear medicine practice. The SPECT and fused SPECT/CT images were reviewed and interpreted separately to determine if addition of the fused CT images added in- cremental information, e.g., more definitive anatomic localization, more definitive diagnostic certainty, or changed final image interpretation compared to the SPECT images alone. Our analysis showed that SPECT/CT provided additional in- formation for image interpretation in 54% (78/144) of cases. In most of these (68/78), the CT data improved localization of abnormal and physiologic findings. Diagnostic certainty was improved in 34/144 cases (24%) and image interpretation was beneficially altered in 18/144 cases (13%). The fusion of anatomical and functional information by hybrid SPECT/CT positively impacts image interpretation and adds diagnostic value over SPECT alone.

  • Diagnostic Performance of Contrast-Enhanced Ultrasound For
    www.nature.com/scientificreports OPEN Diagnostic performance of contrast‑enhanced ultrasound for acute pyelonephritis in children Hyun Joo Jung1, Moon Hyung Choi2, Ki Soo Pai1 & Hyun Gi Kim2,3* The objective of our study was to evaluate the performance of renal contrast‑enhanced ultrasound (CEUS) against the 99m-labeled dimercaptosuccinic acid (DMSA) scan and computed tomography (CT) in children for the diagnosis of acute pyelonephritis. We included children who underwent both renal CEUS and the DMSA scan or CT. A total of 33 children (21 males and 12 females, mean age 26 ± 36 months) were included. Using the DMSA scan as the reference standard, the sensitivity, specifcity, positive predictive value, and negative predictive value of CEUS was 86.8%, 71.4%, 80.5%, and 80.0%, respectively. When CT was used as the reference standard, the sensitivity, specifcity, positive predictive value, and negative predictive value of CEUS was 87.5%, 80.0%, 87.5%, and 80.0%, respectively. The diagnostic accuracy of CEUS for the diagnosis of acute pyelonephritis was 80.3% and 84.6% compared to the DMSA scan and CT, respectively. Inter-observer (kappa = 0.54) and intra-observer agreement (kappa = 0.59) for renal CEUS was moderate. In conclusion, CEUS had good diagnostic accuracy for diagnosing acute pyelonephritis with moderate inter‑ and intra‑observer agreement. As CEUS does not require radiation or sedation, it could play an important role in the future when diagnosing acute pyelonephritis in children. Urinary tract infection (UTI) is a common cause of illness with fever in children. It frequently develops in boys during their frst year of life and is more frequent in girls of older ages 1.

  • Introducing PET/CT at AIMS, Kochi
    Nuclear medicine investigations use small amounts of FDA approved sterile radioactive materials for imaging. These investigations are safe, can be used in all age groups even extremes of age and are painless. Small amounts of radiopharmaceuticals are introduced into the body by injection, swallowing, or inhalation. These radiopharmaceuticals are substances, which are organ specific and get bound within a period of time to the organ and facilitate imaging. The amount of radiopharmaceutical used is carefully selected to provide the least amount of radiation exposure to the patient but ensure an accurate test. A special camera (PET, SPECT gamma camera) is then used to take pictures of your body. The camera detects the radiopharmaceutical in the organ, bone or tissue and forms images that provide data and information about the area in question. Nuclear medicine differs from an x-ray, ultrasound or other diagnostic test because it determines the presence of disease based on biological changes rather than changes in anatomy. Hence it helps in early detection of a disease much before other anatomical imaging modality picks up.

  • Having a DMSA Kidney Scan As an Outpatient
    Medical Physics and Clinical Engineering Department – Information for patients Having a DMSA kidney scan as an outpatient A DMSA kidney scan is a nuclear medicine test of the kidneys. It can be used to detect any damaged areas of the kidneys, for example as a result of repeated urinary tract infections. It is also able to see whether both kidneys are working equally well. Is it safe for me to have the scan? For this scan it is necessary to inject a small amount of radioactive tracer, called a radiopharmaceutical, in order to take the pictures. The small risk from this radiation dose is outweighed by the information that will be gained by having the scan. There is a table of radiation risks at the end of this leaflet. Ask if you want any more information. All investigations are vetted to make sure this is the appropriate test for you. If you don’t understand why you need to have this scan please speak to the doctor who referred you. For female patients If you know that you are pregnant, or there is any chance that you may be pregnant, please contact the department where you will be having the scan. Do this as soon as possible as the scan can be postponed if it is not urgent. Also contact the department if you are breastfeeding, as we may give you special instructions. Preparation for your scan There are no special preparations for a DMSA kidney scan. You can eat, drink and take any medicines as normal. Your injection A small amount of radioactive tracer will be injected into a vein in your arm or hand.

    MEDICAL POLICY – 6.01.502 Single Photon Emission Computed Tomography (SPECT) for Non-cardiac Indications Effective Date: June 1, 2021 RELATED MEDICAL POLICIES: Last Revised: May 4, 2021 6.01.54 Dopamine Transporter Imaging with Single-photon Emission Computed Replaces: N/A Tomography Select a hyperlink below to be directed to that section. POLICY CRITERIA | DOCUMENTATION REQUIREMENTS | CODING RELATED INFORMATION | EVIDENCE REVIEW | REFERENCES | HISTORY ∞ Clicking this icon returns you to the hyperlinks menu above. Introduction SPECT is a type of nuclear imaging test that uses a radioactive dye, also called a tracer, and a special camera to create a three-dimensional (3-D) image of the organs in the body. The images created by tracking the dye in the blood stream can show areas of increased/decreased blood flow and progressive changes in the body. SPECT is proposed to help diagnose or monitor certain tumors, bone disorders, and heart problems. SPECT imaging of the brain for mental health disorders is used as a research tool in clinical trials. Research has not shown the utility of SPECT brain imaging for differential diagnosis or for assessing or predicting an individual’s risk of getting a mental health disorder. Dopamine transporter imaging with single-photon emission computed tomography (DAT- SPECT) is addressed in another policy (see Related Medical Policies). Note: The Introduction section is for your general knowledge and is not to be taken as policy coverage criteria. The rest of the policy uses specific words and concepts familiar to medical professionals. It is intended for providers. A provider can be a person, such as a doctor, nurse, psychologist, or dentist.

Lowe, MD, Anna Nussbaum Blask, MD, and Massoud Majd, MD The pediatric genitourinary tract may be affected by many disor- ders, most of which are congenital and some acquired. Patients pre- senting with signs and symptoms related to the genitourinary tract often need imaging for diagnosis and management. In this article, a problem- oriented approach is used to discuss the following clinical urologic problems: (1) urinary tract infection (UTI), (2) hydronephrosis or hy- droureter, (3) genitourinary trauma, (4) swollen scrotum, and (5) hema- turia. THE CHILD WITH URINARY TRACT INFECTION UTI is one of the most frequently encountered clinical problems in children. Despite the common occurrence of UTI, the diagnostic work- up and management remain a constant challenge for pediatricians. There are many approaches to evaluating children with UTIs; however, the ultimate goal of the diagnostic work-up is to identify kidneys at risk for acute pyelonephritis (AP) and subsequent renal scarring. The task may become simpler by addressing two important questions: Is the infection limited to the bladder, or does it involve the kidney resulting in acute From the Department of Diagnostic Imaging and Radiology, Children’s National Medical Center and The George Washington University Medical School, Washington DC (ESR, A M , MM); and the Department of Radiology, Children’s Medical Center of Dallas, University of Texas-Southwestern, Dallas, Texas (LHL) PEDIATRIC CLINICS OF NORTH AMERICA VOLUME 44 * NUMBER 5 * OCTOBER 1997 1065 1066 SHALABY-RANA et a1 pyelonephritis; and are there underlying anatomic abnormalities in the urinary tract that predispose to infection, most importantly vesicoure- teral reflux (VUR) and obstruction.
