Patellar tendon-Hoffa fat pad interface: From anatomy to high-resolution ultrasound imaging.

Aim: To propose a standardized, high-resolution ultrasound (US) protocol to assess the patellar tendon-Hoffa fat pad interface (PTHFPI) in patients with (proximal) patellar tendinopathy (PPT).

Methods: Using a high-frequency transducer and a high-level machine, we matched the cadaveric and histological microarchitecture of the PTHFPI with multiple sonographic patterns of patients with PPT. Likewise, high-sensitive color/power Doppler assessments were also performed to evaluate the microcirculation of the soft tissues beneath the patellar tendon.

Histo-Anatomy and Sonographic Examination for the Retrocalcaneal Bursal Complex: EURO-MUSCULUS/USPRM Approach.

Insertional Achilles tendinopathy is an umbrella medical term referring to pain and swelling on the posterior aspect of the calcaneus. High-resolution ultrasound imaging is commonly used in daily practice to assess the pathological changes of the Achilles tendon, cortical bone of the calcaneus, and soft tissues located inside the retrocalcaneal space to optimize the management of relevant patients. To the best of our knowledge, a standardized ultrasound protocol to evaluate the retrocalcaneal bursal complex is lacking in the pertinent literature.

Treatment response assessment of acute pyelonephritis: A multi-reader DWI-based MRI approach.

Purpose: To evaluate the diagnostic accuracy of a structured reporting score (SRS) in treatment response assessment for acute pyelonephritis (APN) using a diffusion-weighted imaging (DWI) -based MRI approach. Additionally, we explored the influence of reader experience on the interpretation of SRS and DWI, including lesion conspicuity and measurements of Apparent Diffusion Coefficient (ADC) maps.

Methods: Follow-up DWI-based MRIs of 36 patients treated for APN between September 2021 and June 2023 were retrospectively reviewed by three readers.

Dynamic ultrasound assessment for insertional achilles tendinopathy: the COcco-RIcci (CORI) sign.

Objective: To describe a novel, dynamic ultrasound assessment of the Achilles tendon at the calcaneal insertion taking advantage of the effusion within the deep retrocalcaneal bursa as a natural contrast agent.

Materials And Methods: Positioning the ultrasound transducer in a longitudinal plane over the Achilles tendon at the calcaneal insertion, manual compression of the deep retrocalcaneal bursa can be performed using the other hand. Dynamically shifting the anechoic effusion from the proximal to the distal compartment of the bursa, the undersurface of the Achilles tendon is lifted from the underlying cortical bone of the superior facet of the calcaneal tuberosity.

Ultrasound-Assisted and Ultrasound-Guided Thoracentesis: An Educational Review.

Thoracentesis is one of the most important invasive procedures in the clinical setting. Particularly, thoracentesis can be relevant in the evaluation of a new diagnosed pleural effusion, thus allowing for the collection of pleural fluid so that laboratory tests essential to establish a diagnosis can be performed. Furthermore, thoracentesis is a maneuver that can have therapeutic and palliative purposes.

Isolate scapulothoracic dislocation: Radiological findings and management.

Scapulothoracic dislocation (STD) is a rare condition consisting in the loss of anatomical relations of the scapula with the posterior chest wall. This pathological condition commonly occurs after a scapular region trauma or an upper arm distractive injury. Here-in, we present a case of STD occurring in a young male patient, and we discuss the mechanism of injury, the radiological imaging features, and how it can guide and help the orthopedist in the management.

Aortic dissection: How to identify it during an abdominal ultrasound examination and achieve a potentially lifesaving diagnosis.

Aortic dissection (AD) is a rare and potentially fatal condition that may be diagnosed late. During an emergency or elective abdominal ultrasound (US) examination, when going to evaluate the abdominal aorta for other reasons, it may happen that we find ourselves suspecting an AD. It is therefore important to know the US characteristics of this pathology to avoid wrong or missed diagnoses.

Understanding CEAP Classification: Insights from an Italian Survey on Corona Phlebectatica and Recurrent Active Venous Ulcers by Vascular Specialists.

The clinical relevance of "corona phlebectatica" and the management of risk factors for recurrence of venous ulcers in patients with chronic venous disease may be variable based on vascular specialists in different geographical areas of Italy. The aim of the present survey is to evaluate the management of patients with chronic venous disease by vascular specialists in different areas of the national territory. In particular, this involves ascertaining the clinical/prognostic relevance attributed to the presence of the "corona phlebectatica" as well as to the management of risk factors related to recurrence of venous ulcers.

Ultrasound diagnosis of a pseudoaneurysm of the internal right mammary artery.

One of the principles of managing trauma patients is that of their continuous re-evaluation over the hours and days. Even if the execution of the computed tomography method is classically recommended, especially in the most serious cases and in polytraumas with major dynamics, the clinician can use or request an ultrasound examination, especially in subsequent re-evaluations. Here we report a clinical case demonstrating how an ultrasound re-evaluation after the acute event can lead to a correct diagnosis of a rare complication of thoracic trauma.

Musculoskeletal disorders in padel: from biomechanics to sonography.

Padel is a racket sport, combining high-frequency and low-intensity athletic gestures, that has been gaining growing scientific interest in recent years. Musculoskeletal injuries are very common among padel players with an incidence rate of 3 per 1000 h of training and 8 per 1000 matches. To the best of our knowledge, a comprehensive collection describing the most common sonographic findings in padel players with musculoskeletal injuries is lacking in the pertinent literature.

Multi-omics staging of locally advanced rectal cancer predicts treatment response: a pilot study.

Treatment response assessment of rectal cancer patients is a critical component of personalized cancer care and it allows to identify suitable candidates for organ-preserving strategies. This pilot study employed a novel multi-omics approach combining MRI-based radiomic features and untargeted metabolomics to infer treatment response at staging. The metabolic signature highlighted how tumor cell viability is predictively down-regulated, while the response to oxidative stress was up-regulated in responder patients, showing significantly reduced oxoproline values at baseline compared to non-responder patients (p-value < 10).

Breast ultrasound: An opportunity to detect unsuspected pleural and pulmonary abnormalities.

Purpose: While scanning women for breast US, is possible to observe changes in the appearance of the pleural line or in the most superficial portion of the lung. The objective of this single-center, prospective study was to determine the prevalence of a variety of pleural and pulmonary US findings during routine breast US.

Methods: In this study, there were 200 women undergoing standard breast US examination.

Complications Subsequent to Urinary Tract Stent Placement: An Overview Focusing on the Imaging of Cancer Patients.

Ureteral involvement by a tumor is common, and both partial and complete obstructions can result in symptoms that are distressing and debilitating, especially in cancer patients for whom the resection of the primary tumor is not considered an option. Maintaining ureteric patency in these patients is a challenge. In addition, in cases where a patient has undergone nephroureterectomy due to primary transitional cell cancer, it becomes necessary to decompress the urinary tract to preserve the contralateral kidney from irreversible damage.

Air embolism as a rare complication of lung biopsy: A case report.

Lung biopsy is an important interventional radiology procedure allowing the characterization of lesions with suspected malignancy. The most frequent complications are pneumothorax and hemorrhage. Air embolism is a rare but potentially fatal occurrence.

From Histopathology to High-Resolution Ultrasound Imaging of Skin Scars.

Nowadays, modern ultrasound machines and high-frequency transducers allow us to accurately assess the superficial soft tissues of the human body. In this sense, sonographic evaluation of the skin and related pathologies is progressively growing in the pertinent literature. To the best of our knowledge, a standardized sonographic protocol focused on the assessment of pathological skin scars is still lacking.

Contrast-Enhanced Ultrasound Follow-Up for Acute Pyelonephritis Patients.

Contrast-enhanced ultrasound (CEUS) is increasingly used in clinical practice as the first diagnostic method in patients with suspected pyelonephritis rather than abdominal CT with contrast medium, especially in young subjects. We performed a retrospective analysis on patients in for whom a CEUS examination was utilized as a follow-up method after acute pyelonephritis as normal clinical practice. Through evaluating all patients, in terms duration between CEUS examination and normalization (healing) of the renal disease, we found that the mean duration is 25.

Ultrasound Imaging of the Sciatic Nerve.

The sciatic nerve (SN) is the biggest nerve in the human body and innervates a large skin surface of the lower limb and several muscles of the thigh, leg, and foot. It originates from the ventral rami of spinal nerves L4 through S3 and contains fibers from both the posterior and anterior divisions of the lumbosacral plexus. After leaving the neural foramina, the nerve roots merge with each other forming a single peripheral nerve that travels within the pelvis and thigh.

Incidental Focal Spleen Lesions: Integrated Imaging and Pattern Recognition Approach to the Differential Diagnosis.

Spleen lesions and pseudolesions, detected incidentally in imaging, are not uncommon and may require further work-up. The imaging appearance of focal splenic lesions (FSLs) may not be pathognomonic, because of considerably overlapping features. Consequently, all imaging techniques lack specificity to fully characterize FSLs.

Sonographic guide for botulinum toxin injections for chronic migraine headache: EURO-MUSCULUS/USPRM approach.

Application of botulinum toxin A (BoNT-A) into the muscles of the head and neck area has become a widespread and reliable treatment modality for chronic migraine. The mechanism of action for BoNT-A is the inhibition of acetylcholine and local nociceptive peptide release at the terminal nerve endings. Cranial sutures have the highest concentration of nociceptive structures; therefore BoNT-A injection into the suture lines - as opposed to head and neck muscles - has been proposed for the treatment of chronic migraine.

Isolated adductor longus avulsion in a young semi-professional football player: Imaging contribution and therapeutic considerations.

Adductor longus injuries are usually observed at the proximal musculo-tendinous junction, but isolated tendinous ruptures (i.e., avulsion) at the origin on the pubic bone are uncommon.
