Scientific title | Examination of Pyelonephritis In Children with magnetic resonance imaging (MRI): a cohort study |
Study acronym | EPIC |
Study hypothesis | Magnetic resonance imaging (MRI) can be used as an alternative to dimercaptosuccinic acid (DMSA) for the diagnosis of pyelonephritis in children. |
Ethics approval(s) | METC Noord Holland approved on 30th November 2010, ref: NL32462.094.10 |
Condition | Pyelonephritis |
Intervention | MR-imaging is performed within 8 hours of the DMSA scan. MR examinations of the abdomen and pelvis are performed with the patient in supine position and with a body phased-array coil (better signal-to-noise ratio) on a 1.5-T system (Magnetom Avanto, Siemens, Erlangen, Germany). All MR examinations are performed using a set protocol. Single-shot images (if possible with breath-hold) are made to provide a motion-insensitive image, even in the presence of severe motion. The total examination time is less than 20 min for the MRI in total. The parents can accompany the patient during the examination. If necessary a nurse from the paediatric department may also accompany the patient. |
Intervention type | Other |
Primary outcome measure | 1. The sensitivity, specificity, positive and negative predictive value and inter observer agreement of MRI in diagnosing acute pyelonephritis as compared to the reference standard. 1.1. The MRI findings will be compared to the findings at imaging of the standard diagnostic work-up that preceded MRI. The diagnostic value of specific MRI characteristics for pyelonephritis will be calculated. The value of diffusion-weighted imaging (DWI) will be analysed. |
Secondary outcome measures | 1. To determine whether MR-diffusion weighted imaging (DWI) has additional value in the imaging of pyelonephritis 2. To determine whether MRI scanning can differentiate acute pyelonephritis from renal scarring |

Eligibility
Participant type(s) | Patient |
---|---|
Age group | Child |
Upper age limit | 18 Years |
Sex | Both |
Target number of participants | 80 |
Participant inclusion criteria | 1. Patients from 0 to 18 years, with: 1.1. Acute pyelonephritis, defined as a urinary tract infection (UTI) with a body temperature above 38 °C 1.2. Suspicion of acute pyelonephritis, suggested by symptoms of a UTI and flank pain 2. For young children (under the age of 1 year and in the pre-verbal phase) other clinical symptoms can suggest pyelonephritis. This is bacteriuria with either fever, vomitus, lethargia, anorexia, abdominal pain, pollakisuria or flank pain 3. Outside the study setting, the patient would have received a dimercaptosuccinic acid (DMSA) scan 4. Patients, or a legal representative, must be able to give informed consent, and the consent must be obtained prior to the MR Imaging and DMSA scanning |
Participant exclusion criteria | 1. Previous diagnosis of pyelonephritis 2. All contra-indications for undergoing MRI 3. A psychiatric, addictive, or any disorder that compromises the ability to give truly informed consent for participation in this study |
