The clinical work-up of patients with presumed pancreaticobiliary obstruction is usually straightforward including laboratory investigation, abdominal ultrasound and computer tomography. Ultrasound and computer tomography may, however, yield inconclusive findings regarding underlying cause. We report a case series (n = 10) demonstrating the usefulness of endoscopic ultrasound in the work-up of patients with inconclusive ultrasound and computer tomography findings, clinically suspected of pancreaticobiliary cancer.

Accurately and swiftly segmenting breast tumors is significant for cancer diagnosis and treatment. Ultrasound imaging stands as one of the widely employed methods in clinical practice. However, due to challenges such as low contrast, blurred boundaries, and prevalent shadows in ultrasound images, tumor segmentation remains a daunting task.

Single photon emission computed tomography (SPECT), a technique capable of capturing functional and molecular information, has been widely adopted in theranostics applications across various fields, including cardiology, neurology, and oncology. The spatial resolution of SPECT imaging is relatively poor, which poses a significant limitation, especially the visualization of small lesions. The main factors affecting the limited spatial resolution of SPECT include projection sampling techniques, hardware and software.

Oligorecurrent prostate cancer (PCa) can be treated with metastasis-directed therapy (MDT), which may be performed using radioguided surgery (RGS) as an experimental approach. These procedures have shown promising outcomes, largely due to the high lesion detection rate of positron emission tomography/computed tomography (PET/CT). We present a case series of patients who underwent RGS following robot-assisted radical prostatectomy (RARP).

Peripheral pulmonary lesions (PPLs) present a significant diagnostic challenge due to their location beyond the reach of traditional bronchoscopy. With lung cancer being the leading cause of cancer-related mortality worldwide, accurate and early diagnosis of PPLs is crucial. Virtual bronchoscopic navigation (VBN) combined with radial endobronchial ultrasound (R-EBUS) has emerged as a promising technique to enhance the diagnostic yield for these lesions.
