Capiglioni M, Beisteiner R, Cardoso P, Turco F, Jin B, Kiefer C, et al.
NMR Biomed . 2024 Nov; 38(1):e5280. PMID: 39497348
Spin-lock (SL) pulses have been proposed to directly detect neuronal activity otherwise inaccessible through standard functional magnetic resonance imaging. However, the practical limits of this technique remain unexplored. Key challenges...

Jin B, Capiglioni M, Federspiel A, Ahmadli U, Schindler K, Kiefer C, et al.
Epilepsia Open . 2024 Jul; 9(5):1745-1757. PMID: 38970780
Objective: This study evaluates the performance of the novel MRI sequence stimulus-induced rotary saturation (SIRS) to map responses to interictal epileptic activity in the human cortex. Spin-lock pulses have been...

Schuerch K, Grieder M, Benzing V, Siegwart V, Federspiel A, Slavova N, et al.
Neuropsychol Rehabil . 2024 May; :1-27. PMID: 38809147
Paediatric cancer survivors often suffer from cognitive long-term difficulties. Consequently, strengthening cognition is of major clinical relevance. This study investigated cerebral changes in relation to cognition in non-brain tumour paediatric...

Steiner L, Muri R, Wijesinghe D, Jann K, Maissen-Abgottspon S, Radojewski P, et al.
Neuroimage Clin . 2023 Dec; 41:103550. PMID: 38091797
Background: Phenylketonuria (PKU) represents a congenital metabolic defect that disrupts the process of converting phenylalanine (Phe) into tyrosine. Earlier investigations have revealed diminished cognitive performance and changes in brain structure...

Schuerch K, Grieder M, Benzing V, Siegwart V, Federspiel A, Slavova N, et al.
Dev Neuropsychol . 2023 May; 48(4):186-202. PMID: 37248710
Pediatric cancer survivors (PCS) experience functional difficulties and brain alterations. However, little is known about cerebral perfusion and its relationship to functional outcome (cognitive and motor performance) in PCS. We...

Capiglioni M, Turco F, Wiest R, Kiefer C
Sci Rep . 2022 Oct; 12(1):16965. PMID: 36216858
Extracting quantitative information of neuronal signals by non-invasive imaging is an outstanding challenge for understanding brain function and pathology. However, state-of-the-art techniques offer low sensitivity to deep electrical sources. Stimulus...

Weng G, Radojewski P, Sheriff S, Kiefer C, Schucht P, Wiest R, et al.
Magn Reson Med . 2022 Mar; 88(1):53-70. PMID: 35344608
Purpose: At ultra-high field (UHF), B -inhomogeneities and high specific absorption rate (SAR) of adiabatic slice-selective RF-pulses make spatial resolved spectral-editing extremely challenging with the conventional MEGA-approach. The purpose of...

Talon E, Wimmer W, Hakim A, Kiefer C, Pastore-Wapp M, Anschuetz L, et al.
Eur Arch Otorhinolaryngol . 2022 Jan; 279(10):4793-4799. PMID: 35072767
Purpose: The use of magnetic resonance imaging (MRI) is often limited in patients with auditory implants because of the presence of metallic components and magnets. The aim of this study...

Unger D, Wiest R, Kiefer C, Raillard M, Dutil G, Stein V, et al.
J Vet Intern Med . 2021 Oct; 35(6):2828-2836. PMID: 34623697
Background: The diagnosis of idiopathic epilepsy (IE) in dogs is based on exclusion of other potential causes of seizures. Recently, a novel magnetic resonance imaging (MRI) sequence that utilizes a...

Siegwart V, Steiner L, Pastore-Wapp M, Benzing V, Spitzhuttl J, Schmidt M, et al.
Dev Neuropsychol . 2021 May; 46(3):249-264. PMID: 33969767
Childhood cancer and its treatment puts survivors at risk of low working memory capacity. Working memory represents a core cognitive function, which is crucial in daily life and academic tasks....
