Multiecho Fat‐Water Spiral MR Elastography With Distributed Encoding for Simultaneously Imaging Brain and Skull Displacement

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce a novel multiecho, multishot spiral MR elastography (MRE) sequence to image brain and skull displacement simultaneously using a joint fat‐water image reconstruction and distributed motion encoding. Methods Multiple echo times were implemented into a high‐resolution multishot spiral MRE sequence to capture water‐based brain

Current evidence for lung ultrasound elastography in the field of pneumology: a systematic review

ERJ Open Research
Background and objectives Elastography is a technology that has strongly impacted several medical specialties; however, it is not yet applied as part of standard clinical practice in the field of pulmonology. The objective of this systematic review is to

Respiratory Motion Management in Abdominal MRI: Revisiting the Gap Between Technical Advances and Clinical Translation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT The inherently slow acquisition speed of MRI makes abdominal imaging highly sensitive to respiratory motion artifacts. Since the early days of MRI, the development of respiratory motion compensation techniques has been an active research topic, and this field has seen substantial progress.

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

Portal Hypertension &Cirrhosis, EarlyView.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Advancements in Elastography for Evaluating Fibrosis in Renal Transplants: Current Perspectives

Biomedicines
Renal fibrosis is a leading cause of chronic allograft nephropathy. While renal biopsy remains the gold standard for diagnosing fibrosis, it is an invasive procedure with potential for severe complications.

Head‐to‐Head Comparison of Four Ultrasound Elastography Techniques in Detecting Advanced Fibrosis

Portal Hypertension &Cirrhosis, EarlyView.
Elastography is an important noninvasive method for diagnosing advanced fibrosis (AF); however, evidence remains insufficient, particularly regarding acoustic radiation force impulse (ARFI) techniques. This prospective mulitcenter study concludes that vibration controlled transient elastography (VCTE) demonstrates superior diagnostic performance to ...

Main elastography methods.

, 2018
In strain elastography (or quasi static elastography) (A), the operator press the tissue with imaging transducer. In the second case, the shear wave is generated by acoustic radiation force impulse excitation.

Imaging of Abdominal Complications in Children With Acute Lymphoblastic Leukaemia

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy and remains one of the most common causes of cancer‐related death in children and adolescents. Five‐year overall survival rates now exceed 90% with current multidrug chemotherapeutic regimens. This improvement, coupled with the toxicity of chemotherapy, has led to the
