Imaging Methods and MR Technology

ESMRMB 2025 in Marseille has concluded. IMMRTech values these opportunities for multidisciplinary scientific discussion.

We presented our poster: "Reliability of MRI-derived multispectral neuroimaging measurements after 3T scanner relocation."

Our research investigated the reliability of quantitative MRI data following a scanner's physical relocation. The findings indicate that with proper recalibration, the impact on neuroimaging metrics is minimal, supporting high reproducibility for long-term studies.

We thank our collaborators at CIMeC - University of Trento for their contributions to this work: Alberto Finora, Stefano Tambalo, Jorge Jovicich, and the entire team.

🧪 Clinical Case in Magnetic Resonance Imaging

📢 Follow-up to last post teaser:
In the previous post, we shared two coronal T2 TSE images, one of which revealed a formation in the left submandibular region.

Here is the explanation of the case.

📋 Clinical Presentation:
The examination was performed on a Philips 1T open vertical-field scanner.
An adult female patient reported a "bothersome lump" palpable in the submandibular region, which became more pronounced during specific tongue movements. Standard pre-contrast images did not fully clarify the origin of the symptom.

🛠 Technical Approach:
To improve diagnostic clarity, we asked the patient to replicate the tongue movement that intensified both the sensation and visibility of the lump. This approach yielded more illustrative images, particularly valuable for the case's iconography.

📊 Results (from Radiologist’s report):
The images acquired during the forced movement revealed:
- A slight asymmetry between the sublingual glands, with the left one herniating through a discontinuity of approximately 1 cm in the mylohyoid muscle (an anatomical variant).
- During the movement, the left sublingual gland shifted inferiorly into the submandibular space, extending nearly 1 cm beyond the inferior margin of the left hemimandible and displacing the anterior belly of the digastric muscle.

💡 Conclusions:
This case highlights the importance of tailoring imaging protocols: a small adjustment, such as asking the patient to perform a specific maneuver, can make the images clearer and support the entire clinical team's work.

Artifact correction in Multi-Echo MPRAGE.
The artifact seen in the unfiltered scan (First slide, red arrow) originates from data in the first column of k-space (kx=0) during the receive path. This can be easily corrected by applying a raw filter, found under the “Resolution > Filter RawData” tab in Siemens scanners (Second slide, red arrow), resulting in an artifact-free image (Third slide, red arrow).

📢 Le iscrizioni alla Seconda Edizione del Master di Primo Livello in Risonanza Magnetica: Tecniche di acquisizione, ottimizzazione e analisi di immagini dell'Università di Verona apriranno il 4 novembre 2024!

Un'ottima occasione per i Tecnici Sanitari di Radiologia Medica che desiderano approfondire le proprie competenze nell'ambito della Risonanza Magnetica, migliorando le loro capacità sia nel campo clinico che nella ricerca biomedica.

Siamo felici di essere nuovamente partner in questa entusiasmante avventura!
