Automated CT Image Processing for the Diagnosis, Prediction, and Differentiation of Phenotypes in Chronic Lung Allograft Dysfunction After Lung Transplantation

Stefan Kuhnert, N. S. S. Halim, Janine Sommerlad, Henning Gall et autres

BACKGROUND: Chronic lung allograft dysfunction (CLAD) after lung transplantation is a common complication with a poor prognosis. We assessed the utility of quantitative computed tomography (CT) for the diagnosis, prediction, and discrimination of CLAD phenotypes. METHODS: We retrospectively analyzed routine inspiratory and …

Anogenital distance on MRI does not correlate to surgical diagnosis of endometriosis in patients without prior abdominal surgery

Sebastian Harth, Lena Metze, Daniel Leufkens, Fritz Roller et autres

Anogenital distance (AGD) is regarded as a potential biomarker for endometriosis, and a measurement on MRI images has been found to be promising. This study aimed to evaluate the measurement of AGD on MRI to predict the surgical diagnosis of endometriosis. We …

Non-invasive surrogate markers of pulmonary hypertension are associated with poor survival in patients with cancer

Michael Cekay, Philipp Friedrich Arndt, Johanna K Franken, Jochen Wilhelm et autres

BACKGROUND: Cancer is one of the leading causes of death worldwide, and cardiopulmonary comorbidities may further adversely affect cancer prognosis. We recently described lung cancer-associated pulmonary hypertension (PH) as a new form of PH and comorbidity of lung cancer. While patients with …

Native hepatic T1-time as a non-invasive predictor of diastolic dysfunction and a monitoring tool for disease progression and treatment response in patients with pulmonary hypertension

Nils Kremer, Fritz Roller, Sarah Kremer, Simon Schäfer et autres

AIMS: Hepatic T1-time derived from cardiac magnetic resonance imaging (cMRI) reflects venous congestion and may provide a simple alternative to invasive end-diastolic elastance (Eed) for assessment of right ventricular (RV) diastolic function. We investigated the association of native hepatic T1-time with single-beat …

Non-invasiv quantifiziertes RV-PA Coupling als unabhängiger Prädiktor für das Überleben beim NSCLC

Z Rako, Michael Cekay, S Yildiz, Chris M Mummert et autres

Hintergrund : Das Bronchialkarzinom (BK) stellt global die führende Todesursache neoplastischer Erkrankungen dar. Patienten mit BK weisen ein vermehrtes Vorkommen von Komorbiditäten, insbesondere kardiopulmonal, auf, welche prognosebestimmend sein können. Zuletzt war die Pulmonale Hypertonie (PH) im Rahmen des BK als Komorbidität vermehrt …

Native hepatische T1-Zeit als nicht-invasiver Prädiktor der diastolischen Dysfunktion und als Verlaufsparameter für Krankheitsprogression und Therapieansprechen bei Patienten mit pulmonaler Hypertonie

Nils Kremer, Fritz Roller, Sarah Kremer, Manfred Richter et autres

Hintergrund : Die pulmonale Hypertonie (PH) kann zu einer diastolischen Dysfunktion des rechten Ventrikels (RV), in der Folge zu einer venösen Stauung und damit zu einer Kongestion abhängiger Organe (v.a. Leber und Niere) führen. Sequenzen der kardialen Magnetresonanztomographie (cMRT) enthalten Schnittbilder der …

Molecular Iodine Optical Atomic Clocks

Jonathan Roslund, A. Cingöz, Abijith S. Kowligy, Michael T. Ledbetter et autres

Vector Atomic has developed optical clocks using iodine vapor cells. These clocks provide excellent short-term instability, require neither laser cooling nor cavity pre-stabilization, are insensitive to motion, and maintain holdovers of <1ns for several days.

Cystic echinococcosis, a rare differential diagnosis of cystic pelvic masses

Sebastian Harth, Fritz Roller, Felix Zeppernick, Ivo Meinhold‐Heerlein et autres

Introduction As a second-line imaging modality for leiomyomas (syn. fibroids) to sonography in clinical routine, MRI offers the advantages of a large field-of-view, multiplanarity and excellent soft-tissue contrast. MRI can accurately aid therapeutical planning (surgical and interventional) and helps in the detection …
